Question 420909:
This is the problem I am trying to work out. I have tried foiling, quadratic equation, completing the square, but I am not coming up with a good answer. If you could help me I would appreciate it. I don't want to know the answer as much as how to do it.

;
square both sides

:
FOIL the Left side
(x+2) - + (x-3) = (x-6)
:
Combine like terms, move the radical to right
x + x -x + 2 - 3 + 6 =
;
FOIL inside the radical
x + 5 =
:
square both sides
x^2 + 10x + 25 = 4(x^2 - x - 6)
x^2 + 10x + 25 = 4x^2 - 4x - 24
:
Combine like terms on the right
0 = 4x^2 - x^2 - 4x - 10x - 24 - 25
:
3x^2 - 14x - 49 = 0
Factors to
(3x + 7)(x - 7) = 0
positive solution is all want here
x = + 7
:
:
Check solution in the original equation

you can see that it checks out
