About the Course
In this course, Professor Keith Ball (University of Warwick) explores solving equations, covering Topics A17-A18 in the Pearson Edexcel GCSE (9-1) Mathematics (1MA1) Specification for Foundation Tier. In the first mini-lecture, we give an introduction to solving equations and think about what it means to ‘solve’ and equation. In the second mini-lecture, we discuss how to solve linear equations and how to approximate solutions to linear equations using a graph (Topic A17). In the third mini-lecture, we consider how to solve quadratic equations by factorising and by using the special properties of zero (Topic A18). In the fourth mini-lecture, we learn how to approximate solutions to quadratic equations by graphing (Topic A18).
