Quadratic vocabulary quiz: MCQ test! Is math not that difficult? There are different ways that one can solve a quadratic expression, and the quiz below is designed to help see just how equipped you are to solve different problems. Do take up the quiz and get to see if you might need a refresher in solving quadratic equations. Keep an eye out for more quizzes just like it when you get done.

• 1.

### What is an expression?

• A.

A formula with an equals sign.

• B.

A formula with a plus sign.

• C.

A formula without a plus sign.

• D.

A formula without an equals sign.

D. A formula without an equals sign.
Explanation
An expression is a mathematical statement that does not include an equals sign. It can consist of numbers, variables, and operators such as plus, minus, multiplication, and division. Unlike an equation, which requires an equals sign to show a relationship between two expressions, an expression is simply a mathematical phrase that can be evaluated or simplified. Therefore, the correct answer is "A formula without an equals sign."

### Which best describes a quadratic equation?

• A.

An equation that has something raised to the second power.

• B.

An equation that has 2x as one of it's terms.

• C.

An equation that has no power that is greater than 2.

• D.

An equation where x is raised to the second power and that is the highest power on x.

D. An equation where x is raised to the second power and that is the highest power on x.
Explanation
A quadratic equation is an equation where x is raised to the second power and that is the highest power on x. This means that the equation can have terms with x raised to the power of 1 or 0, but it cannot have any terms with x raised to a power greater than 2. The other options do not accurately describe a quadratic equation as they either refer to a general equation with something raised to the second power or specific terms in an equation, rather than the overall characteristics of a quadratic equation.

Rate this question:

• 3.

### What is a polynomial?

• A.

An expression or equation with more that one term.

• B.

An expression or equation with one term.

• C.

An expression or equation with x raised to the second power and no higher power on x.

• D.

An expression or equation with three terms.

A. An expression or equation with more that one term.
Explanation
A polynomial is defined as an expression or equation with more than one term. This means that it consists of multiple terms added or subtracted together. Each term in a polynomial can have different variables and exponents, but they are all combined using addition or subtraction. This is in contrast to an expression or equation with only one term, which would not be considered a polynomial. Additionally, the definition of a polynomial does not specify any specific exponent or number of terms, so options 3 and 4 are not accurate explanations.

Rate this question:

• 4.

### The roots of a quadratic function tell you what about the function?

• A.

What the highest power is.

• B.

Where the graph of the function crosses the y-axis.

• C.

Where the graph of the function crosses the x-axis.

• D.

How many times the graph changes direction.

C. Where the graph of the function crosses the x-axis.
Explanation
The roots of a quadratic function represent the values of x for which the function equals zero. In other words, they are the x-coordinates of the points where the graph of the function intersects or crosses the x-axis. Therefore, the correct answer is "Where the graph of the function crosses the x-axis."

Rate this question:

• 5.

### A trinomial has _________ terms in it.

three
3
Explanation
A trinomial is a polynomial with three terms. Therefore, the correct answer is "three" or "3".

Rate this question:

• 6.

### Another word for the zero's of a quadratic functions is ___________.

Solutions
Roots
x-intercepts
x intercepts
Explanation
The correct answer is "solutions, roots, x-intercepts, x intercepts." In mathematics, the zeros of a quadratic function are the values of x where the function equals zero. These values can also be referred to as solutions, roots, x-intercepts, or x intercepts because they represent the points where the graph of the quadratic function intersects the x-axis.

Rate this question:

• 7.

### What is the vertex of a quadratic function?

• A.

The Maximum point of the quadratic.

• B.

The Minimum point of the quadratic.

• C.

The point that if you folded it, it would match up perfectly.

• D.

A and B.

• E.

None of these.

D. A and B.
Explanation
The vertex of a quadratic function is the point where the graph reaches its maximum or minimum value. In the case of a quadratic function, the vertex can be either the maximum point or the minimum point, depending on whether the parabola opens upwards or downwards. Therefore, the correct answer is A and B, as both options represent the possible positions of the vertex.

Rate this question:

• 8.

### What is the axis of symmetry?

• A.

￼The Maximum point of the quadratic.

• B.

The Minimum point of the quadratic.

• C.

The point that if you folded it, it would match up perfectly.

• D.

A and B.

• E.

None of these.

C. The point that if you folded it, it would match up perfectly.
Explanation
The axis of symmetry is the vertical line that divides a parabola into two symmetric halves. If you fold the parabola along this line, the two halves would perfectly match up. Therefore, the correct answer is "The point that if you folded it, it would match up perfectly."

Rate this question:

• 9.

### The standard form of a quadratic is like _____________

ax^2+bx+c
y=ax^2+bx+c
Explanation
The standard form of a quadratic equation is represented as ax^2+bx+c, where a, b, and c are coefficients. This form allows for easy identification of the leading coefficient (a), the coefficient of the linear term (b), and the constant term (c). The equation y=ax^2+bx+c is another way of representing the same quadratic equation in terms of the dependent variable y. Both forms are commonly used in mathematics to solve and analyze quadratic equations.

Rate this question:

• 10.

### The greatest common factor in an expression is the __________ thing that divides into every term.

biggest
Explanation
The greatest common factor in an expression is the largest number or term that can evenly divide into every term of the expression.
