We'll cross multiply and we'll get the cleared
equation:
(x-1)(x+1) =
(x-3)(x+2)
We notice that we'll get a difference of 2
squares to the left side. We'll remove the brackets from the right
side:
x^2 - 1 = x^2 + 2x - 3x -
6
x^2 - 1 = x^2 - x - 6
We'll
remove the like terms and we'll get:
-1 = -x -
6
We'll shift all terms to the left
side:
x + 6 - 1 = 0
We'll
combine like terms:
x + 5 =
0
x = -5
The
solution of the equation is x = -5.
