$factor the following trinomial. $h^2 + 6h - 55$ $(h - ?)(h + \\square)$$

factor the following trinomial.
$h^2 + 6h - 55$
$(h - ?)(h + \square)$

We need two numbers that multiply to $-55$ and add to $6$. The pair is $-5$ and $11$, since $(-5) \times 11 = -55$ and $-5 + 11 = 6$.

Substitute the numbers into the given form $(h - [?])(h + [])$.

$(h - 5)(h + 11)$
