Question

If f(x) = 3x^2 – 2x + 4 and g(x) = 5x^2 + 6x – 8, find (f - g)(x).

Answer 1

(f-g)(x)=f(x)-g(x)

=((3x^2)-2x+4)-((5x^2)+6x-8)

=(-2x^2)-8x+12

The answer is -2x^2 -8x+12. I hope this helps.

Answer 2

`-2x^2-8x+12`

Explanation:

`f-g=(3x^2-2x+4)-(5x^2+6x-8)=3x^2-2x+4-5x^2-6x+8=\\ =-2x^2-8x+12`
