### Factorising quadratics at a glance

Factorising quadratics involves factorising quadratic algebraic expressions into double brackets. This means rewriting a quadratic expression so that it is a product of two factors with each factor written as an expression inside a bracket.

Factoring quadratics involves quadratics with a coefficient of 1 for the x² term. This can be done by looking at the constant term and finding its factor pairs and calculating which pair sum to make the coefficient of the x term.

We also need to use factorising quadratic expressions of the form ax²+bx+c. This can be done by using a similar method that first involves multiplying the coefficient of the x² term by the constant.

Factorising quadratic equations can be used to solve quadratic equations. This can help us plot the solutions to quadratic equations on quadratic graphs.

Looking forward, students can then progress to additional algebra worksheets, for example a solving equations with fractions worksheet or  simultaneous equations worksheet.
