#### Home / Interactive Lessons / Algebra / GCSE / Year 11 Term 1 Students learn to solve quadratic equations by factorising  when the coefficient of x2 is one.  As learning progresses they are challenged to rearrange quadratics to equal zero and set up and solve equations from known geometrical facts.
##### Differentiated Learning Objectives
• All students should be able to solve a quadratic equation in the form x2+bx+c using factorisation.
• Most students should be able to solve a quadratic equation in the form x2±bx±c using factorisation.
• Some students should be able to derive and solve an equation using known geometrical facts.
