4x/x-5 + 2/x = -4/x-5
Multiply every term by LCD x(x-5)
4x*x + 2(x-5) = -4x
4x^2 + 2(x-5) = -4x
4x^2 + 2x-10 = -4x
4x^2 + 2x-10 +4x = 0
4x^2 +6x -10=0
2(2x+5)(x-1) =0
2x+5=0 or x-1=0
x=-5/2 or x=1 <--------- Answers

If you multiply both sides by , the
equation will still be true
Use the quadratic formula to solve
and
You can check these 2 solutions by plugging back into
