# How do you factor 20x^6-25xy?

May 23, 2015

You take out of the equation everything that is multiplying all elements:

$4 \cdot \textcolor{g r e e n}{5 \cdot x} \cdot x \cdot x \cdot x \cdot x \cdot x - 5 \cdot \textcolor{g r e e n}{5 \cdot x} \cdot y$

$\left(5 x\right) \left(4 {x}^{5} - 5 y\right)$
