# How do you write y = -2(x+4)(x+1) in standard form?

Apr 18, 2018

Using FOIL, we get $y = - 2 {x}^{2} - 10 - 8.$

#### Explanation:

$y = - 2 \left(x + 4\right) \left(x + 1\right)$

Using FOIL:

$y = - 2 \left({x}^{2} + x + 4 x + 4\right)$

$y = - 2 {x}^{2} - 10 x - 8$

That's standard form so we stop.
