Answer 1

binomial has 2 terms when simplified

a. x^2, only 1 term
b. x2-4x^2=-3x^2, 1 term
c. x^2-4 , 2 terms, binomial
d. 2x^2+3x-1y, 3 terms, trinomial

answer si C

Answer 2

Answer: $x^2 - 4$

Step-by-step explanation:

Since a Binomial is an algebraic expression of the sum or the difference of two terms.

Therefore, For a binomial an expression must contain exactly two terms.

In a) $x^2$ there is only one term therefore it is not the Binomial.

In a) $x^2-4x^2 = -3x^2$,  there is only one term therefore it is not the Binomial.

In a) $x^2-4$ there is exactly two terms therefore it is a Binomial.

In a) $2x^2+3x-1y$ there are three terms therefore it is not the Binomial.
