Questions and Answers
  • 1. 

    Find the factors for the following equation: -6x2 - 3x + 6

    • A.

      7 and 21

    • B.

      6 and 18

    • C.

      2 and 4

    Correct Answer
    A. 7 and 21
    Explanation
    The factors of the equation -6x^2 - 3x + 6 are 7 and 21 because when these values are multiplied together and added to the other terms in the equation, they result in a sum of zero.

    Find the factors for the following equation: x2 - 4x - 60 **Enter your answers with no spaces and with the smaller factor first. EX: (x-2)(x+1)

    Correct Answer
    (x-10)(x+6)
    Explanation
    The correct answer is (x-10)(x+6). This is because when we factor the equation x^2 - 4x - 60, we need to find two numbers that multiply to give -60 and add up to -4. The numbers -10 and 6 fit this criteria, as -10 * 6 = -60 and -10 + 6 = -4. Therefore, the factors of the equation are (x-10)(x+6).

    Find a, b, and c for the following equation: x+ 7x + 12 **Enter your answers starting with a separated with commas and with no spaces unless after the comma. EX: a=1, b=2, c=3

    Correct Answer
    a=1, b=7, c=12
    Explanation
    The given equation is in the form of ax^2 + bx + c, where a=1, b=7, and c=12.

  • 4. 

    Find a, b, and c for the following equation: 9x2 = 4 + 7x **Enter your answers starting with a separated with commas and with no spaces unless after the comma. EX: a=1, b=2, c=3

    Correct Answer
    a=9, b=-7, c=-4
    Explanation
    The given equation is a quadratic equation in the form of ax^2 + bx + c = 0. In order to find the values of a, b, and c, we can compare the given equation with the standard form of a quadratic equation. By comparing the coefficients of x^2, x, and the constant term, we can determine that a = 9, b = -7, and c = -4.

    Find the factors for the following equation: x2 - 11x + 24 **Enter your answers with no spaces and with the smaller factor first. EX: (x-2)(x+1)

    Correct Answer
    (x-8)(x-3)
    Explanation
    The given equation is a quadratic equation in the form of ax^2 + bx + c. To find the factors, we need to factorize the quadratic equation. The factors of the equation x^2 - 11x + 24 are (x-8)(x-3).

    Find the factors for the following equation: 6x2 - 5x - 4 **Enter your answers with no spaces and with the smaller factor first. EX: (x-2)(x+1)

    Correct Answer
    (3x-4)(2x+1)
    Explanation
    The given equation is a quadratic equation in the form of ax^2 + bx + c. To find the factors, we need to factorize the equation into two binomial expressions. The factors of the equation 6x^2 - 5x - 4 are (3x - 4) and (2x + 1).

  • 7. 

    Find the factors for the following equation: 6x2 + 7x - 49 **Enter your answers with no spaces and with the smaller factor first. EX: (x-2)(x+1)

    Correct Answer
    (3x−7)(2x+7)
    Explanation
    The given equation 6x^2 + 7x - 49 can be factored as (3x - 7)(2x + 7).

  • 8. 

    Find the factors of the following equation: 2x2 + 3x - 20

    • A.

      Option 1

    • B.

      Option 2

    • C.

      Option 3

    Correct Answer
    B. Option 2
    Explanation
    The factors of the equation 2x^2 + 3x - 20 can be found by factoring the equation. Option 2 is the correct answer because it provides the correct factors of the equation.

  • 9. 

    2 + 2x - 5 = 0. Solve for x.

    • A.

      2

    • B.

      5

    • C.

      0

    • D.

      1.5

    Correct Answer
    D. 1.5
    Explanation
    To solve the equation 2 + 2x - 5 = 0, we need to isolate the variable x. First, we combine like terms by adding 2 and -5, which gives us 2x - 3 = 0. Then, we add 3 to both sides of the equation to get rid of the -3, resulting in 2x = 3. Finally, we divide both sides of the equation by 2 to solve for x, which gives us x = 1.5.

    Rate this question:

  • 10. 

    If 1/x is infinity, what is x?

    • A.

      0

    • B.

      1

    • C.

      1/2

    • D.

      None of the above

    Correct Answer
    A. 0
    Explanation
    If 1/x is infinity, it means that x must be 0. This is because any number divided by 0 is undefined, and therefore the only value that can make the expression 1/x equal to infinity is when x equals 0.
