How do you solve 5y^2=30y?

Jul 14, 2018

$y = 0$ or $y = 6$

Explanation:

Writing your equation in the form
$5 y \left(y - 6\right) = 0$
so we get

$y = 0$ or $y = 6$

$y = 0$ and $y = 6$

Explanation:

We have a second-degree term, so this is beginning to look like a quadratic. Let's subtract $30 y$ from both sides to find the zeroes:

$5 {y}^{2} - 30 y = 0$

We can factor a $5 y$ out, and we get

$5 y \left(y - 6\right) = 0$

Setting both factors equal to zero, we get

$y = 0$ and $y = 6$

Hope this helps!
