Penjelasan dengan langkah-langkah:
[tex]\begin{aligned}\displaystyle\rm~f(x) &= \displaystyle\rm~ \frac{ {x}^{2} - 4x}{x + 5} \\ \\ \displaystyle\rm~f(10)& = \displaystyle\rm~ \frac{ {10}^{2} - 4(10)}{10 + 5} \\ \\ & = \displaystyle\rm~ \frac{100 - 40}{15 } \\ \\ &= \displaystyle\rm~ \frac{60}{15} \\ \\ & = \displaystyle\rm~4\end{aligned}[/tex]
