x^2-2x-24

To factor this expression we have to find the following


(x+A)(x+B)

Where


\begin{gathered} A\cdot B=-24\to(1) \\ A+B=-2\to(2) \end{gathered}

we solve (1) and (2) to find our values of the factorization


\begin{gathered} A=4 \\ B=-6 \\ A\cdot B=-24=4\cdot(-6) \\ A+B=-2=4-6 \\ \end{gathered}

So the factor of the expresion is


x^2-2x-24=(x+4)(x-6)
