g(x)-f(x)=2x^2-5x

Explanation:

Given the following functions, you are asked to subtract f(x) from g(x):

1. color(darkorange)(f(x)=x+2)
2. color(blue)(g(x)=2x^2-4x+2)

Thus:

color(blue)(g(x))-color(darkorange)(f(x))

=color(blue)(2x^2-4x+2)-color(orange)((x+2))

Simplify.

=2x^2-4x+2-x-2

=color(green)(|bar(ul(color(white)(a/a)2x^2-5xcolor(white)(a/a)|)))
