A4

simplify and manipulate algebraic expressions (including those involving surds and algebraic fractions) by:

• collecting like terms

• multiplying a single term over a bracket

• taking out common factors

• expanding products of two or more binomials

• factorising quadratic expressions of the form x^2 + bx + c, including the difference of two squares; factorising quadratic expressions of the form ax^2 + bx + c

• simplifying expressions involving sums, products and powers, including the laws of indices
