The width, w, of a rectangular garden is x – 2. The area of the garden is x^3 — 2x – 4. What is an expression for the length of the garden? (1 point)
x^2 – 2x – 2
x^2 + 2x – 2
x^2 – 2x + 2
x^2 + 2x + 2

******** -6 x^2 + 4 x + 3
********____________________________
(3x+2) | -18 x^3 + 0 x^2 + 17 x + 6
*********-18 x^3 -12 x^2
*****************12 x^2 + 17 x + 6
*****************12 x^2 + 8 x
*************************9 x + 6
*************************9 x + 6
remainder = 0
================================
(x^3 - 2 x - 4) /(x-2)
do it long division as above
******________________________
(x-2) | x^3 + 0 x^2 - 2 x - 4
get x^2 + 2 x + 2
