Question 889164: i need help describing and correcting the error
(3/x) + 6/(x+3)=8/(x+1)
LCD=x(x+3)(x+1)
3(x+3)(x+1)=6x(x+1)=8
3(x^2+4x+3)+6x^2+6x=8
3x^2+12x+9+6x^2+6x=8
9x^2+18x+1=0

What about the right hand side?
3%28x%2B3%29%28x%2B1%29%2B6x%28x%2B1%29=8x%28x%2B3%29
3%28x%5E2%2B4x%2B3%29%2B6x%5E2%2B6x=8x%5E2%2B24x%29
3x%5E2%2B12x%2B9%2B6x%5E2%2B6x-8x%5E2-24x=0
x%5E2-6x%2B9=0
%28x-3%29%5E2=0
x-3=0
x=3
