Question

X^2-4x-12 factor the expression

Answer 1

I have not taken algebra in 20 years, and have an algebra class left to complete my associates. Ive been reviewing like crazy, but much of this is still stumping me and I feel behind so I'll be coming in here a bit to see if I can get help, and find a tutor at the college. Im making progress, but its SLOW, and PAINFUL, and time-consuming. Have to do this when my kids are at school in order to have peace to study.

Anyway, stuck on something here, I'll give you part of the problem below:

CODE: SELECT ALL

3               1                4
---      +   ---      =     -----
X+6          x-2           x(2) + 4x - 12

The section x(2) + 4x - 12 in the book is show factored to (x+6)(x-2)

This is done to also find the LCD.

I dont understand how it got to (x+6)(x-2)??

Answer 2

I hope this helps you
