  1. Factorising
    • find common factors
    • find 2 numbers which multiply to give c and add to give b

  2. Splitting the Middle term!




    (a,b,c are integers)
    • 1. find ac
    • 2. find 2 numbers (p&q)
    •       pq=ac
    •       p+q=b
    • 3. use p&q to split middle term
    • arrange into bracket by taking out common factor! (same bracket =1st bracket outside numbers =2nd bracket)
  3. Solving equations by factorisation!
    • factorise the question into brackets
    • p and q equal the roots of the graph
    • if both brackets are the same the graph only touches its root.
  4. Complete the square
    • 1. Halve the middle term
    • 2. put this in a bracket with x and square the bracket
    • 3. compare expanded form with what is required and adjust
  5. Solving linear inequalities
    solve the same way as an equation!

    if you divide or multiply by a negative flip the sign!

    you cant square or root both sides of an inequality!
