E.g.1 Expand these expressions: • 6(x + 3) • 2(6 - 5x) - 3(2 + 2x) - 4(3x - 1) • -5x(3x + 4) • 8 - (4 - d) - (6 - d) • 3(x + 4) - 2(x - 5) • (e + f - g) - (e - f + g) E.g.2 Multiply binomial expressions Simplify i. (a + 2)(a + 3) iv. (2x + 3) 2 ii. (2x + y)(2x - y) v. (x - 2x) 2 iii. multiply (3x - 2y) by (3x + 2y) vi. (a + 2) 2
