# How do you Factor completely: 5a^2 + b?

Apr 7, 2018

No common factors$\implies$ cannot be factored

#### Explanation:

$5 {a}^{2}$ and $b$ have no common factors, thus this is not factorable.

If we had $5 {a}^{2} + a$, this would be factorable, because both terms have an $a$ in them. This would be
$a \left(5 a + 1\right)$
