Find f(x) - g(x) when f(x) = 2x^2 - 4x g(x) = x^2 + 6x 3x^2

x^2 + 2x

x^2 - 10x

3x^2 + 2x

x^2 - 10x

Step-by-step explanation:

2x^2 - 4x - x^2 +6x

You subtract x^2 from 2x^2 and you get x^2

Then you add 6x and 4x together and get 10x

So then you have x^2 - 10x

(plus I took the test and this was the correct answer.)

i think the answer is 90 hope this
