Question

What is the difference of the two polynomials? (9x2 + 8x) – (2x2 + 3x) A 7x2 + 5x  B.7x2 + 11x C.11x2 + 5x  D.11x2 + 11x

Answer 1

the answer is A

Explanation:

Answer 2

we have

`(9x^(2) + 8x)-(2x^(2) + 3x)`

Remove parentesis

`9x^(2) + 8x-2x^(2) -3x`

Combine like terms

`9x^(2) -2x^(2) + 8x -3x`

`7x^(2) + 5x`

therefore

the answer is

`7x^(2) + 5x`
