Converting Quadratic Equations:
Learn to switch between the general form, $ax^2 + bx + c$, and the vertex form, $a(x – h)^2 + k$, (where $a \neq 0$).
Converting Vertex Form to General Form:
Square the binomial, expand the brackets, and simplify to rewrite a quadratic equation in general form.
Converting General Form to Vertex Form:
Factor out the coefficient of $x^2$, then complete the square to rewrite the equation in vertex form.
