Question

(5x cubed- 8x squared + 9x) -(9xsquared+3x+8)

Answer 1

(5x^3-8x^2+9x)-(9x^2+3x+8)
First you should remove the parentheses. These means distributing the negative from the subtraction sign across the 2nd set.

So:

5x^3 - 8x^2 + 9x - 9x^2-3x-8.

Then you combine like terms:

5x^3-17x^2+6x-8
