factor the equation
2006-10-23 05:34:24 · update #1
(x + 2) (x - 3)
First figure out how to get 6. You could either use 6 x 1 or 3 x 2. 3 x 2 is the best choice because you get -1 if you subtract 3 from 2 (which is what you want in the middle term. Then you have to note that x^2 can only come from 2 x's so you put that in the beginning. The nest step is figuring out where to put your + and - . In this equation the + goes with the 2 and the - goes with the 3 because it equals -1 when put together.

X= -2
or X=3

It's like this
x^2-x-6
(x-3)(x+2)---;reason: -3+2 = -1 -3*2 = -6
(x-3)(x+2)
the factors are 3 & -2

(x^2-x-6) = (x-3)(x+2)

x^2-x-6
Since -3 and 2 equals to -6 and -3+2=-1, the problem would look like this:
(x-3)(x+2)
Check:
(x-3)(x+2)=
x^2-3x+2x-6=
x^2-x-6

this is easy one
(x-3)(x+2)
so the value of x are 3 and -2

(x2-x-6)
=x2-3x+2x-6
=x(x-3)+2(x-3)
=(x+2)(x-3)
this method is called splitting the middle term
u could also use factor theorem
