Question

Add, subtract, multiply, and divide What is (f+g)(x)? f(x)=-3x^(2) g(x)=2x^(2)-9x

Answer 1

`x^2 - 9x`

Explanation:

f(x) + g(x)

`-3x^2 + 2x^2 -9x`

`x^2 - 9x`

If it requires you to solve for x, then the answer would be:

`x^2 - 9x=0\\`

`x(x-9)=0` (here you are factoring the x)

`x=0 \\x-9=0, x=9`
