# How do you write y = 5x^3 - 5x^2 - 10x in factored form?

Sep 15, 2015

$y = 5 x \left(x - 2\right) \left(x + 1\right)$
First, there is a factor of 5x so I would factorise that first. This yields; $y = 5 x \left({x}^{2} - x - 2\right)$
Then you need to factorise the quadratic function which will then take you to the final solution of $y = 5 x \left(x - 2\right) \left(x + 1\right)$
