Solve simple quadratic equations using a range of strategies (ACMNA241)

* identifying the connection between algebraic and graphical solutions of equations (for example understanding that the x-intercepts are the solutions of f(x) = 0) exploring the method of completing the square to factorise quadratic expressions and solve quadratic equations
