Question

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

Answer 1

Simplify:

`\begin{gathered} (x)/(x+5)+(7x+10)/(x^2+5x) \\ (x^2)/(x(x+5))+(7x+10)/(x^2+5x) \\ (x^2+7x+10)/(x(x+5)) \\ ((x+5)(x+2))/(x(x+5)) \\ \end{gathered}`

Hence the required result is

`((x+2))/(x)`

Result:

option (D) is correct
