Question 639152: I need help solving the following equation. The only instructions listed on the page is "Solve." I get confused on how to even start. Foil? Common denominator? I don't know what the like term would be. Please help me solve the following:
+%281%2Fx%29%2B%281%2F%281%2Bx%29%29=%28-3%29%2F%28x%5E2%2Bx%29%29+

You can put this solution on YOUR website!
you are right about - start from common denominator
+1%2Fx%2B1%2F%281%2Bx%29=%28-3%29%2F%28x%5E2%2Bx%29%29+
+1%2Fx%2B1%2F%281%2Bx%29=%28-3%29%2Fx%28x%2B1%29%29+
%28+1%2Bx%2Bx%2B3%29%2Fx%281%2Bx%29=0+
%28+2x%2B4%29%2Fx%281%2Bx%29=0+
The fraction is equal 0, when the numerator is equal 0 and the denominator is not equal 0
2x%2B4=0
x=-2
