  2. Factorise these quadratic expressions Hint - attention to detail is critical 2x2 - 9x - 5 x2 + 6x + 5 x2 + 4x - 5 2x2 + 11x + 5 2x2 + 9x - 5 2x2 - 3x - 5 2x2 -11x + 5 2x2 + 3x - 5 2x2 - 7x + 5 x2 - 6x + 5 2x2 + 7x + 5 x2 - 4x - 5

  3. Activity cards Cut out the cards and investigate the relationship between the factors x2 + 6x + 5 x2 + 4x - 5 2x2 - 9x - 5 2x2 + 11x + 5 2x2 + 9x - 5 2x2 - 3x - 5 2x2 -11x + 5 2x2 - 7x + 5 2x2 + 3x - 5 x2 - 6x + 5 x2 - 4x - 5 2x2 + 7x + 5

  4. Hint cards Use these cards to help factorise the quadratic expressions (2x - 5) (2x + 1) (x + 1) (x + 5) (x - 5) (x - 1) (2x - 1) (2x + 5)

  5. Solution (x + 5) (x - 5) (2x - 5) (2x + 5) (x + 1) 2x2 - 3x - 5 2x2 + 7x + 5 x2 + 6x + 5 x2 - 4x - 5 (x - 1) x2 + 4x - 5 x2 - 6x + 5 2x2 + 3x - 5 2x2 - 7x + 5 Attention to detail is essential for success (2x + 1) 2x2 - 9x - 5 2x2 + 11x + 5 (2x - 1) 2x2 -11x + 5 2x2 + 9x - 5
