In mathematics, a polynomial is an expression that needs to be operated. Polynomial expressions usually have variables and coefficients that needs to be divided or multiplied. Factors of a polynomial expression are that which yield the polynomial when they are multiplied. Do you know how to factorize polynomial expressions?

Questions and Answers

1.

What are variables in polynomials called?
- A.
  
  Symbols
- B.
  
  Articles
- C.
  
  Indeterminates
- D.
  
  Coefficients
Correct Answer
C. Indeterminates

Explanation
Variables in polynomials are called indeterminates because they represent unknown quantities or values. In polynomials, these variables are raised to various powers and combined with coefficients to form terms. The indeterminates allow for the expression of general relationships and equations without specifying specific values. They are often represented by symbols such as x, y, or z, and their powers determine the degree of the polynomial.

Which of these does not employ factorization of polynomials?
- A.
  
  Numerical analysis
- B.
  
  Complex analysis
- C.
  
  Arithmetic
- D.
  
  Calculus
Correct Answer
C. Arithmetic

Explanation
Arithmetic does not employ factorization of polynomials because arithmetic deals with basic operations like addition, subtraction, multiplication, and division of numbers, not with the factorization of polynomials. Factorization of polynomials is a concept that is typically studied in algebra or algebraic mathematics.

Which of these does not require the use of polynomials?
- A.
  
  Polynomial rings
- B.
  
  Algebraic variety
- C.
  
  Algebraic geometry
- D.
  
  Number system
Correct Answer
D. Number system

Explanation
The number system does not require the use of polynomials. The number system is a mathematical concept that includes all the numbers we use in everyday life, such as integers, fractions, decimals, and irrational numbers. It is not directly related to polynomials, which are algebraic expressions consisting of variables and coefficients. Polynomial rings, algebraic variety, and algebraic geometry, on the other hand, are all branches of mathematics that involve the study of polynomials and their properties.

Which of these operations is not supported by polynomials?
- A.
  
  Division
- B.
  
  Exponentiation
- C.
  
  Multiplication
- D.
  
  Logarithm
Correct Answer
D. Logarithm

Explanation
Polynomials are mathematical expressions consisting of variables and coefficients, combined using addition, subtraction, and multiplication. They do not involve division or exponentiation. Logarithm, on the other hand, is a mathematical operation that determines the exponent to which a base must be raised to obtain a certain number. Since logarithms are not a part of polynomial operations, they are not supported by polynomials.

Which of these is not possible in all polynomial expressions?
- A.
  
  Distributivity
- B.
  
  Commutativity
- C.
  
  Infinity
- D.
  
  Associativity
Correct Answer
C. Infinity

Explanation
Infinity is not possible in all polynomial expressions because a polynomial expression is a finite sum of terms, each consisting of a variable raised to a non-negative integer exponent, multiplied by a coefficient. Therefore, the concept of infinity, which represents an unbounded or limitless quantity, is not applicable in the context of polynomial expressions.

What is the degree of a constant term when factoring polynomials?
- A.
  
  2
- B.
  
  10
- C.
  
  1
- D.
  
  0
Correct Answer
D. 0

Explanation
The degree of a constant term when factoring polynomials is 0. This is because the degree of a term is determined by the highest power of the variable in that term. A constant term does not have any variables, so it does not have any power associated with it. Therefore, the degree of a constant term is 0.

What are polynomials with real coefficients called?
- A.
  
  Special polynomial
- B.
  
  Integer polynomial
- C.
  
  Real polynomials
- D.
  
  Complex polynomials
Correct Answer
C. Real polynomials

Explanation
Polynomials with real coefficients are called real polynomials. This means that all the coefficients in the polynomial are real numbers. Real polynomials can have real roots and can be graphed on the real number line. They are widely used in various mathematical applications and are an important concept in algebra.

What is a polynomial with two indeterminates called?
- A.
  
  Complex polynomial
- B.
  
  Univariate polynomial
- C.
  
  Multivariate polynomial
- D.
  
  Bivariate polynomial
Correct Answer
D. Bivariate polynomial

Explanation
A polynomial with two indeterminates is called a bivariate polynomial. The term "bi" in bivariate refers to two, indicating that the polynomial has two variables. In this case, the polynomial has two indeterminates, which means it can have terms with both variables raised to different powers. This is different from a univariate polynomial, which has only one variable, and a multivariate polynomial, which can have more than two variables. Therefore, the correct answer is bivariate polynomial.

What law allows factorized polynomials to be added?
- A.
  
  Communitative law
- B.
  
  Associative law
- C.
  
  Horner's law
- D.
  
  Laplace principle
Correct Answer
B. Associative law

Explanation
The associative law states that the order in which numbers are added does not affect the sum. In the context of factorized polynomials, this means that the order in which the polynomials are added does not affect the result. Therefore, the associative law allows factorized polynomials to be added.

Which of these is not used to analyse factorized polynomials on graphs?
- A.
  
  Intercepts
- B.
  
  Slope
- C.
  
  Shape
- D.
  
  Concavity
Correct Answer
C. Shape

Explanation
The shape of a factorized polynomial on a graph is used to analyze its behavior and determine the number and type of roots it has. The shape refers to the overall curve of the graph and the direction it is moving. Intercepts are used to find the points where the graph crosses the x or y-axis, slope is used to determine the steepness of the graph, and concavity is used to analyze the curvature of the graph. Therefore, the correct answer is "Shape" because it is not used to analyze factorized polynomials on graphs.
