Feb 3, 2016

$y = \left(x + 1\right) \left(x + 2\right)$

#### Explanation:

$y = {x}^{2} + 3 x + 2$

Find two numbers that when added equal, $3$, and when multiplied equal $2$. The numbers $1$ and $2$ fit the pattern.

Factor the quadratic equation as two binomials.

$y = \left(x + 1\right) \left(x + 2\right)$
