2. Factorise the following 10x a – 20 36m a + 27b + 9c 9y² - 12y 30ab³ + 35a²b 24x4y³ - 40x²y

3. Expand and simplify the following
(x + 7)(x + 5)
(x - 4)(x + 5)
(3x - 2)(x - 6)
(2x + 1)(5x - 2)
(x + 7)²
(4x + 3)²

4. Factorise the following
x² + 8x + 6
x² - 7x + 12
x² - 2x - 35
x² + x + 56
x² - 49
x² - 121

5. Solve
4x+2=3x+12 10x-3=5x+27 3x - 6 = 10 – x 6x + 2 = x 5(2x + 3) = 8x + 23
x² + 15x + 26 = 0
x² + 2x - 24 = 0
x² - 81 = 0
