1
Factor the trinomial $x^2-x-2$ finding two numbers that multiply to form $-2$ and added form $-1$
$\begin{matrix}\left(1\right)\left(-2\right)=-2\\ \left(1\right)+\left(-2\right)=-1\end{matrix}$
2
Rewrite the polynomial as the product of two binomials consisting of the sum of the variable and the found values
$f\left(x\right)=\left(x+1\right)\left(x-2\right)$
Final answer to the problem
$f\left(x\right)=\left(x+1\right)\left(x-2\right)$
