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

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

f(x) - g(x) = 2x^2 - 4x - (5-2x)
f(x) - g(x) = 2x^2 - 4x - 5 + 2x
f(x) - g(x) = 2x^2 - 2x - 5 
for x = 5
f(x) - g(x) = 2(5)^2 - 2(5) - 5 
f(x) - g(x) = 50 - 10 - 5
f(x) - g(x) = 50 -15
f(x) - g(x) = 35

Answer is C. 35
