\left(\frac{\left(x-2\right)\left(x+2\right)}{x+2}+\frac{4}{x+2}\right)\times \frac{6x+12}{x_{2}}
To add or subtract expressions, expand them to make their denominators the same. Multiply x-2 times \frac{x+2}{x+2}.
\frac{\left(x-2\right)\left(x+2\right)+4}{x+2}\times \frac{6x+12}{x_{2}}
Since \frac{\left(x-2\right)\left(x+2\right)}{x+2} and \frac{4}{x+2} have the same denominator, add them by adding their numerators.
\frac{x^{2}+2x-2x-4+4}{x+2}\times \frac{6x+12}{x_{2}}
Do the multiplications in \left(x-2\right)\left(x+2\right)+4.
\frac{x^{2}}{x+2}\times \frac{6x+12}{x_{2}}
Combine like terms in x^{2}+2x-2x-4+4.
\frac{x^{2}\left(6x+12\right)}{\left(x+2\right)x_{2}}
Multiply \frac{x^{2}}{x+2} times \frac{6x+12}{x_{2}} by multiplying numerator times numerator and denominator times denominator.
\frac{6\left(x+2\right)x^{2}}{x_{2}\left(x+2\right)}
Factor the expressions that are not already factored.
\frac{6x^{2}}{x_{2}}
