$36\left(x^2-1\right)=0$

Learn how to solve rational equations problems step by step online. Solve the equation (36(x^2-1))/((x^2+3)^3)=0. Multiply both sides of the equation by \left(x^2+3\right)^3. Divide both sides of the equation by 36. We need to isolate the dependent variable x, we can do that by subtracting -1 from both sides of the equation. Removing the variable's exponent.
