Question

Which of the following is a binomial? (2 points) c2 + c + 6 c2 − 16 −8c c3 + 4c2 − 12c + 7

Answer 1

In maths, for an expression to be called a binomial, this expression must:
1- have only two terms
2- exponents of the terms must only be positive integers (not fractions or negative integers)
3- if the two terms have the same variable, then the exponent of the variable in each term must be different from that of the other term

Note:
an expression with only one term is called monomial while an expression with only three terms is called trinomial

Comparing the definition of binomial to the given choices, we will find that the correct choice is:
c^2 - 16

Answer 2

The binomial is c2-16
