Question

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

Answer 1

Answer: (f+g)(x)=8x^2+4x-4

Explanation:

Answer 2

-2x^2-8x+12

Explanation:

f(x) = 3x^2-2x+4

g(x) = 5x^2+6x-8

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

Distribute the minus sign

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

Combine like terms

=-2x^2-8x+12
