Quadratic Equations
Your child will handle every quadratic the board paper can pose, from factorisation to the discriminant, without hesitation. Quadratics generally bring around six to seven marks, often a three-mark solution plus a question on the nature of roots. The chapter opens with standard form and the meaning of a root, then teaches solving by factorisation, solving by completing the square, the quadratic formula derived from that completion, and the discriminant test that predicts two distinct roots, equal roots or no real roots. It closes with word problems on numbers, areas and motion where only one r
