Removal of brackets Example Work out each of the following 4 x 36 = 4x(30+6) 5 x 18 = 5x(10+8) 6 x 72 =6x(70+2)

Example Remove the bracket for the expression 3(a + 4) Example Remove the bracket for the expression 5(2b + 5)

Example Remove the bracket for each of the following expression 2(2y + 5) = 4y + 10 4(5m + 3) = 20m + 12 7(3r – 4) = 21r – 28 8(2p – 7) = 16p – 56 4(5m + 3n) = 20m + 12n 3(6k – 5d) = 18k – 15d a(a + 3) = a2 + 3a b(3b – 8) = 3b2 – 8b

Example Remove the brackets for each of the following 4(3c + 7) 7(2r – 8) t(t – 5) 8(3m – 1) a(4a + 9) 3(3e + 2f) b(2 + 5b) h(3h – 9) 2y(3y – 5)
