SOLUTION: Solve: x+4/x^2-x-2=6/x^2-4x-5 I've gotten so far as x^2=32/-7, but I'm pretty sure it's not right.

Question 245144: Solve: x+4/x^2-x-2=6/x^2-4x-5 I've gotten so far as x^2=32/-7, but I'm pretty sure it's not right.

Solve: x+4/(x^2-x-2) = 6/(x^2-4x-5)
---
Factor:
(x+4)/[(x-2)(x+1)] = 6/[(x-5)(x+1)]
---
Multiply both sides by (x+1):
---
(x+4)/(x-2) = 6/(x-5)
Cross-multiply and solve for "x":
x^2-x-20 = 6x-12
x^2-7x-32 = 0
---------------------
Quadratic Formula:
x = [7 +- sqrt(49-4*-32)]/2
---
x = [7 +- sqrt(177)]/2
