# What is the standard form of  y= x(x+2) -(x+3)^2 ?

Apr 10, 2018

$y = - 4 x - 9$

#### Explanation:

Well, this depends on what your standard form is. The practical standard form of a second-power parabola would go like this: $y = a {x}^{2} + b x + c$ . If you want to use this standard form, it will go like this:

$y = x \left(x + 2\right) - {\left(x + 3\right)}^{2}$

$y = \left({x}^{2} + 2 x\right) - \left({x}^{2} + 6 x + 9\right)$

$y = - 4 x - 9$

So, in this problem, you have a basic, non-exponential form.
