Which polynomial represents the difference below?
ser-zykov [4K]

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.
