What is the resulting equation after we clear the fractions? Do not solve the equation.
| $\frac{8}{\left(x+6\right)\left(x-6\right)}$8(x+6)(x−6) | $=$= | $\frac{5}{x-6}+\frac{4}{x+6}$5x−6+4x+6 |
| $\left(x+6\right)\left(x-6\right)\cdot\frac{8}{\left(x+6\right)\left(x-6\right)}$(x+6)(x−6)·8(x+6)(x−6) | $=$= | $\left(x+6\right)\left(x-6\right)\left(\frac{5}{x-6}+\frac{4}{x+6}\right)$(x+6)(x−6)(5x−6+4x+6) |
