Question

Which polynomial represents the difference below?

Answer 1

The difference for the given polynomial is ${5x^2-2x+4}$

Explanation:

The given polynomial is $(8x^2+9)-(3x^2+2x+5)$

A polynomial is generally a sum or difference of terms or variables which are separated by addition and subtraction signs. There are "three types of polynomial": Monomial, binomial and trinomial.

The difference between is found as follows:

D = $(8x^2+9)-(3x^2+2x+5)$

Removing the brackets, we get,

D = $8x^2+9-3x^2-2x-5$

D = $5x^2+4-2x$

D = $5x^2-2x+4$

Thus, the polynomial represents Option A as the difference.
