Question

F(x) = 3x + 5
g(x) = 4x^2 – 2
h(x) = x^2 – 3x + 1

Find f(x) – g(x) – h(x).

Answer 1

f(x) – g(x) – h(x) = -5x^2 + 6x + 6

Explanation:

Copy f(x) as is: f(x) = 3x + 5

Negate g(x): -g(x) = -4x^2 + 2

Negate h(x): -h(x) = -x^2 + 3x - 1

Now combine like terms:

f(x) – g(x) – h(x) = -5x^2 + 6x + 6
