# How do you solve (6h-5)(6h+5)=0?

Apr 23, 2018

$h = \frac{5}{6}$ or $h = - \frac{5}{6}$

#### Explanation:

Why do these come up in the feed if they're two years old?

$\left(6 h - 5\right) \left(6 h + 5\right) = 0$

$6 h - 5 = 0$ or $6 h + 5 = 0$

$h = \frac{5}{6}$ or $h = - \frac{5}{6}$

$h = \frac{5}{6} , - \frac{5}{6}$

#### Explanation:

From the null factor law, we know that if the product of two numbers is 0 then either one or both of the numbers has to equal 0. In this case your 'numbers' are $6 h - 5$ and $6 h + 5$
Therefore;
6h - 5 = 0
6h = 5
$h = \frac{5}{6}$
and /or
6h + 5 = 0
6h = -5
$h = - \frac{5}{6}$
