Introducing Quadratics – small steps
Give students a selection of x's and ones.
factor x factor = product
3 x (x+2) = 3x + 6
Expand Three Linear Expressions
First step to factorise quadratics
Difference of Two Squares
Use the sliders to move a+b and a-b to the correct place on the diagram to the right.
Use the a and b sliders to change the size of square a and square b.
Compare the graph to the expanded and factorised form of the quadratic.
x^2 + x - 6 (x + 3)(x - 2)
