Question

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

Answer 1

`y=-4x-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=ax^2+bx+c` . If you want to use this standard form, it will go like this:

`y=x(x+2) -(x+3)^2`

`y = (x^2 +2x)-(x^2+6x+9)`

`y=-4x-9`

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