Answered 2 years ago

Step 1

1 of 2Using the factoring of trinomials in the form $x^2+bx+c,$ the given expression

$\begin{align*} x^2-2x-63 \end{align*}$

has $c= -63$ and $b= -2 .$

The two numbers with a product of $c$ and a sum of $b$ are $\left\{ -9,7 \right\}.$ Using these two numbers, then the factored form of the given expression is

$\begin{align*} (x-9)(x+7) .\end{align*}$
