Notes

To convert an equation in the form of (x^2-3x) into a square equivalent, you half the second value, then square that value (in this case 3) (x-\frac{3}{2})^2, resulting in an equation like this.

Forms

Standard form (vertex form)

 a(x - h)^2 + k 

To convert to standard form given a vertex of a quadratic equation and a point that falls along that line, plug values in for everything and solve for a.

Quadratic form

 y = a^2 + bx + c
