Part 3 / 4 in a sequence of lessons covering solving quadratic equations by factorising.
This lesson covers factorising (and solving) quadratics with positive coefficients using the grid method.
Sequence is:
Part 1: Introduction to solving graphically (to build understanding that some equations have more than 1 solutions)
Part 2: Solving factorised quadratics (undertstanding that one of the 2 linear product has to be 0 if their product is 0)
Part 3: Factorising (and solving) monic quadratics using the grid method - when b and c are positive
Part 4: Factorising (and solving) monic quadratics using the grid method - when b or/and c are negative
This lesson teaches students to factorising monic quadratic equations with positive coefficients using the grid method.
It finishes by solving (as solving factorised quadratics was covered in the previous lesson).
