x=-2+-sqrt29

Explanation:

50/x+2=2x+10

First, you would exclude the solution x=0 and then multiply all the terms by x:

x!=0 and 50+2x=2x^2+10x

Then get it in the standard form and solve it by the quadratic formula:

2x^2+8x-50=0 or, dividing all the terms by 2:

x^2+4x-25=0

x=-2+-sqrt(4+25) (simplified formula x=-b/2+-sqrt((b/2)^2-c))

x=-2+-sqrt29
