Pls if f(x) = 2x^2-4x and g(x) =5-2x, evaluate f(x)-g(x) for x=5

To solve this equation you need to first start by writing out the f(x)-g(X).
The equation should be 2x^2-4x-5+2x. 
You then want to simplify the equation, I got 2x^2-2x-5.
You then want to plug in the x=5 for all the x's in the equation. 
2(5)^2-2(5)-5 would be the equation. 
The answer you get should be 35.
