Foundations of Quadratics

Quadratics

Quadratic expressions and functions in general form \(ax^2+bx+c\), factored form \(a\left(x-\alpha\right)\left(x-\beta\right)\), and vertex form \(a\left(x-h\right)^2+k\), including factoring, completing the square, the quadratic formula, roots/x-intercepts, vertex, axis of symmetry \(x=-\frac{b}{2a}\), and concavity from the sign of \(a\).
