# How do you multiply (5x-1/3)^2?

Jun 21, 2016

$= 25 {x}^{2} - \frac{10 x}{3} + \frac{1}{9}$

#### Explanation:

Multiply the bracket by itself: There will be 4 terms.

${\left(5 x - \frac{1}{3}\right)}^{2} = \left(5 x - \frac{1}{3}\right) \left(5 x - \frac{1}{3}\right)$

$= 25 {x}^{2} - \frac{5 x}{3} - \frac{5 x}{3} + \frac{1}{9}$

$= 25 {x}^{2} - \frac{10 x}{3} + \frac{1}{9}$
