$a^2-11a-42$

Step-by-step Solution

1

Factor the trinomial $a^2-11a-42$ finding two numbers that multiply to form $-42$ and added form $-11$

$\begin{matrix}\left(3\right)\left(-14\right)=-42\\ \left(3\right)+\left(-14\right)=-11\end{matrix}$
2

Rewrite the polynomial as the product of two binomials consisting of the sum of the variable and the found values

$\left(a+3\right)\left(a-14\right)$

Final answer to the exercise

$\left(a+3\right)\left(a-14\right)$
