In this section, we will look at the following topics:

  • What is Algebra? – what algebra is, including definitions of algebraic expressions and equations, constants and variables and like and unlike terms; how to simplify algebraic expressions by adding and subtracting like terms; and, how to simplify algebraic expressions by multiplying and dividing.
  • Expanding brackets and factorising – expand either one or two sets of brackets in an algebraic expression; factorise an algebraic expression using one set of brackets; and, factorise a particular type of quadratic using two sets of brackets.
  • Rearranging and solving linear equations – the definition of a linear equation; techniques for rearranging linear equations; and, how to rearrange a linear equation in order to solve for the value of a variable.
  • Rearranging and solving quadratic equations – the definition of a quadratic equation; how to solve a quadratic equation when b = 0; how to solve a quadratic equation by factorising; and, how to solve a quadratic equation using the quadratic formula.
