Question

Please Help





use synthetic division and the given factor to completely factor the polynomial.

x^3-x^2-24x-36;(x-6)

Show all work

Answer 1

Do you know synthetic division?
YouTube has several examples.

Answer 2

no can you help walk me through the problem?

Answer 3

Rather than explain by typing I will see if I can find a good video:

Answer 5

can you just try to explain? my computer cant handle videos all too well

Answer 6

Divide x^3-x^2-24x-36 by (x-6) using synthetic division.
Write the coefficients of the numerator:
1 -1 -24 -36
To divide by x - 6 take the opposite sign of -6. That will be +6

________________________
6 | 1 -1 -24 -36
| 6 +30 +36
|_____________________________
1 5 6 0

Last line is quotient: x^2 + 5x + 6 Remainder = 0

x^3-x^2-24x-36 = (x-6)(x^2 + 5x + 6)
x^2 + 5x + 6 is a quadratic expression which you can factor.
