Question

Note: Enter your answer and show all the steps that you use to solve this problem in the space provided. f ( x ) = 9 x 3 + 2 x 2 − 5 x + 4 fx=9x3+2x2-5x+4 and g ( x ) = 5 x 3 − 7 x + 4 . g(x)=5x3-7x+4. what is f ( x ) − g ( x ) ? f(x)-g(x)? Show all of your steps and write your final answer in factored form.

Answer 1

Answer:

2x(2x²+x+1)

Dtep-by-step explanation:

f(x) = 9x³+2x²-5x+4

g(x) = 5x³-7x+4

f(x) - g(x)

= 9x³+2x²-5x+4 - (5x³-7x+4)

= 9x³+2x²-5x+4-5x³+7x-5

= 4x³+2x²+2x

= 2x(2x²+x+1)
