What is the difference of the polynomials? (9x^2 + 8) = (2x^2 + 3x)?

7x^(2) - 3x + 8

Step-by-step explanation:

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

distribute the "-" sign.

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

Now combine like terms; (an "x^(2)" goes with an "x^(2)", not with an "x")

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

7x^(2) - 3x + 8
