  1. Factorise x² + x − 6

    Show answer

    (x + 3)(x − 2)

  2. Factorise x² + 5x + 6

    Show answer

    (x + 2)(x + 3)

  3. Factorise x² − 121

    Show answer

    (x + 11)(x − 11)

  4. What is the general form for factorising a difference of two squares x² − a²?

    Show answer

    (x + a)(x − a)

  5. Factorise y² − 9w²

    Show answer

    (y + 3w)(y − 3w)

  6. Factorise 2y² + 7y − 15

    Show answer

    (2y − 3)(y + 5)

  7. Factorise fully 2y² − 50

    Show answer

    2(y² − 25) = 2(y + 5)(y − 5)

  8. If Freddy factorises x² − 11x + 30 as (x + 5)(x + 6), what is his mistake?

    Show answer

    Both factors should be negative: (x − 5)(x − 6), because the x coefficient is negative and the constant is positive.

  9. Factorise 3x² + 4xy + y²

    Show answer

    (3x + y)(x + y)

  10. Factorise fully (x + 4)² + 3(x + 4)

    Show answer

    (x + 4)(x + 7)

  11. If 10x² + 9x + 2 = (5x + 2)(2x + 1), what is the factorisation of 10(y − 3)² + 9(y − 3) + 2?

    Show answer

    (5(y − 3) + 2)(2(y − 3) + 1) = (5y − 13)(2y − 5)
