Multiplying out Single Brackets Brackets are often used in algebra, for example 3 x (x - y) is usually written as 3(x - y).Multiplying out brackets is often known as 'expanding brackets'. To expand brackets, each term inside the bracket is multiplied by the term outside the bracket.ExamplesExpand...1) 3(a - b)= 3 x a - 3 x b=3a - 3b2) x(2x - 3y)= x times 2x - x times 3y= 2x squared - 3xy3) 5(x - 3) +2(x - 1)=5x -15 +2x - 2=7x -174) 3(2x - 1) -2(x +1)=6x - 3 - 2x - 2=4x - 5
