2.38 The Quadratic Formula Higher GCSE PowerPoint Lesson

This 29-slide lesson introduces the quadratic formula as a method for solving any quadratic equation, including those that cannot be factorised. Students will practise applying the formula to find both exact solutions in surd form (without a calculator) and rounded solutions to a given degree of accuracy. The lesson also explores the role of the discriminant in determining the number and type of solutions: two distinct, one repeated, or no real solutions. By the end, students will be able to interpret and communicate solutions both algebraically and in context.
