Exercise 1 1 Which of the following simplify to p? a b c d 2 These triangles are similar but not congruent. Are the following true or false? a b c d TIP An equation is two expressions linked by an ‘=’ sign, for example, 2 + 2x = 4x. An identity is an equation where the expressions on either side of the = sign are exactly the same when simplified. For example: 2x + 3x = 4x + x 3 Which one of these is an identity? Explain your answer. a b 4 Which of these are identities? a b c ...

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. ...
