Solutions Of Equations
Akopọ
What happens when a straight line meets a parabola, or when a cubic polynomial has roots you need to find? This topic equips you with the algebraic strategies for handling systems where at least one equation is nonlinear, and for cracking open cubic equations that contain at least one rational root.
You will learn to combine substitution with quadratic methods to solve simultaneous equations involving a line and a curve, and you will apply the factor theorem to reduce cubic equations to a product of factors you can solve completely. These techniques appear in nearly every Edexcel 4PM1 paper and carry significant marks.
