ALGEBRA REVIEW 4) Formulae Substitution The formula t = v – u a is used to calculate time (t). If v = 21, u = 6 and a = 3, calculate what t will be? If v = 14, u = 2 and t = 3, calculate what a is? Substitution a = 3, b = 5, c = -2, d = 10 (a) 3b – d (b) ac + b (c) b(4a – 3) (d) a(2b + c) 4 Expand brackets Expand 3(4y – 5) Expand m(3m + 5) Expand 4(2w – 3) + 2(3w + 9) Expand 5(2y + 1) – 3(3y – 2) Expand (p + 3)(p + 5) Shape algebra Calculate the perimeter and area of this rectangle 3 4n - 1 Objective Mastered I can expand single brackets    I can expand separate brackets I can expand double brackets I can factorise expressions into single brackets I can substitute into expressions I can substitute into formulae I can solve algebra problems in shapes 2) Factorise Factorise 6b – 10 Factorise a² + 3a Factorise 20a – 15ab
