Suppose f(x) = x + 1, g(x) = x^2 + 3, and h(x) = 4x^2 - x + 2. Evaluate f(x) middot g(x) - h(x).

Solution

f(x) = x+1

g(x) = x^2 + 3

h(x) = 4x^2 - x + 2

f(x) * g(x) = (x+1)(x^2 + 3)

f(x) * g(x) = x^3 + 3x + x^2 + 3 = x^3 + x^2 + 3x + 3

f(x)* g(x) - h(x) = x^3 + x^2 + 3x + 3 - ( 4x^2 - x + 2 )

f(x)* g(x) - h(x) = x^3 - 3x^2 + 4x + 1
