Question

HELP!!
(x^3-2x^2-5x+6)/(x+2)

Answer 1

x=1
x=3

Answer 2

solutions

Answer 3

you can use factor theorem.
f(x) = x^3+2x^2-5x-6
f(-1) = -1+2+5-6 = 0
x+1 is a factor

use synthetic division,
x^3+2x^2-5x-6 = (x+1)(x^2+x-6) = (x+1)(x-2)(x+3) = 0

therefore, the solution is x = -1, 2, -3

Answer 4

polynomial

Answer 5

yes
