Question

Please help me with this quickly, which step has a mistake?

Answer 1

Simplify:

$\begin{gathered} \frac{x}{x+5}+\frac{7x+10}{x^2+5x} \\ \frac{x^2}{x(x+5)}+\frac{7x+10}{x^2+5x} \\ \frac{x^2+7x+10}{x(x+5)} \\ \frac{(x+5)(x+2)}{x(x+5)} \\ \end{gathered}$

Hence the required result is

$\frac{(x+2)}{x}$

Result:

option (D) is correct
