# Solving Complex Quadratics by Factorising # Solving Complex Quadratics by Factorising

In this mathematics lesson students learn how to solve quadratics in the form ax2+ bx + c = 0 through factorisation.  As learning progresses the factorisation becomes more challenging as the coeffecient of x2is no longer a prime number.
##### Differentiated Learning Objectives
• All students should be able to solve a quadratic in the form ax2 + bx + c = 0 where a is prime and b and c are both positive.
• Most students should be able to solve a quadratic in the form ax2+ bx + c = 0 where a is prime.
• Some students should be able to solve a quadratic in the form ax2 + bx + c = 0 where is not prime.
