Figuring out a quadratic equation from points or graphs? Use systems of equations and solve for \(a\), \(b\), and \(c\) in \(ax^2 + bx + c = 0\). It's algebra puzzle time!
When given vertex form, use \(y = a(x-h)^2 + k\). Just replace \(a\), \(h\), and \(k\) with the provided values to find your equation.
If you forget everything else, remember: \(ax^2 + bx + c = 0\). That's the beauty of quadratics!
