Expand means multiply out an expression to get rid of the brackets. Exercise 1 1 Multiply out and simplify if possible. a b c d e f g h i j k WORKED EXAMPLES Expand and simplify these expressions. a b Solutions a 3(x + 2y) − (x − 3y) You can write ‘1’ before the second bracket before multiplying out. 3(x + 2y) − 1(x − 3y) Multiply each term inside the brackets by the term at the front of the brackets. Be careful with signs. 3x + 6y − 1x + 3y Collect like terms. ...
