Answer 2

Standard form: \(ax^2+bx+c\)

You might want to convert the standard form to vertex form

First factor out the 2 from the vertex equation [a value] \([a(x-h)^2+k]\)

Then use the equation \(h=\large \frac{-b}{2a}\) [from the standard form equation I previously showed] to find the vertex (which is (h,k) )
