What is the difference of the two polynomials? (9x2 + 8x) – (2x2 + 3x) 7x2 + 5x 7x2 + 11x 11x2 + 5x 11x2 + 11x
Anuta_ua [19.1K]

we have

(9x^{2}+8x)-(2x^{2}+3x)

Step 1

Eliminate the parenthesis

(9x^{2}+8x)-(2x^{2}+3x)=9x^{2}+8x-2x^{2}-3x

Step 2

Group terms that contain the same variable

9x^{2}-2x^{2}+8x-3x

Step 3

Combine like terms

7x^{2}+5x

therefore

the answer is

7x^{2}+5x
