You can put this solution on YOUR website!
You didn't use parentheses so I'm guessing here.
2%2F%282x%2B4%29=-12%2F4x
1%2F%28x%2B2%29=-3x
1=-3x%28x%2B2%29
1=-3x%5E2-6x
3x%5E2%2B6x%2B1=0
3%28x%5E2%2B2x%2B1%29-2=0
3%28x%2B1%29%5E2=2
%28x%2B1%29%5E2=2%2F3
x%2B1=0+%2B-+sqrt%282%2F3%29
x=-1+%2B-+sqrt%282%2F3%29
x=-1+%2B-+sqrt%286%29%2F3
