Question 277025
How could I solve this equation dealing with fractions.
x/x+4 - 2 = 12/x-12

x- 2(x+4) / x+4 = 12 / x-12

x-2x-8 / x+4=12/ x-12

(-x-8)(x-12)=(x+4)*12

-x^2+12x-8x+96=12+48

-x^2+4x+96-60=0

-x^2+4x+36=0

x^2-4x-36=0

in the equation a=1, b=-4, c=-36

x1= 4 +sqrt(16+144) /2

=8.325

x2= 4-sqrt(16+144) /2

=-4.325
