Question

(x3 - 18x2 +95x - 126) ÷ (x -9)

a. x2 + 9x + 14

b. 9x2 - 9x + 14

c. x2 - 9x + 14

d. x3 -9x2 + 14x + 126

Answer 1

Two steps:

1. Factor numerator:
\[x^3-18 x^2+95 x-126\]
\[(x-9) (x-7) (x-2)\]


2. Divide out the (x-9) as if it was just another variable itself
\[(x-7) (x-2)\]

Answer 2
