Given f(x)= -x-3 ; g(x)= x^2 -2x+1 ; and h(x)= -2x ; find g x f x h

Question

The x's in the last sentence are supposed to be multiply signs sorry.

Answer 1

g(x) f(x) h(x) =( x² - 2x +1 ) (-x-3) ( -2x)

= ( x² - 2x +1 ) ( 2x² + 6 x )

= 2 x⁴ + 6x³ - 4 x³ - 12x² + 2x² + 6x

= 2 x⁴ + 2 x³ - 10 x² + 6 x

Answer 2

f(x) = -x - 3

g(x) = x² - 2x + 1

h(x) = -2x

g(x) * f(x) * h(x) = (x² - 2x + 1) (-x - 3) (-2x)

= (x² - 2x + 1) (2x² + 6x)

= 2x⁴ - 4x³ + 2x² + 6x³ - 12x² + 6x

= 2x⁴ + 2x³ - 10x² + 6x
