I can factorise quadratics of the form x^2 + bx + c including using the difference of two squares.
Factorise - To factorise is to express a term as the product of its factors.
Quadratic - A quadratic is an equation, graph, or sequence whereby the highest exponent of the variable is 2
Absolute value - The absolute value of a number is its distance from zero.
Once shown the difference of two squares, pupils may think that squaring each term in a binomial is the correct way to expand binomials such as (x+3)^2
Spend time investigating where the difference of two squares occurs, use representations such as algebra tiles and area models.
