Year 9

Note that we cover the second half of the first resource listed below (where we covered solving by factorising earlier in the year). Specific learning objectives this time:

(a) 'Complete the square' to put a quadratic in the form (x + a)2 + b
(b) Extension: Complete the square where the coefficient of the x2 term is not 1.
(c) Solve quadratics by completing the square.
(d) Extension: Identify the minimum/maximum point of a quadratic by completing the square.
(e) Solve quadratic equations by use of the quadratic formula.
