The expression can be simplified to * + 4 x+3 : * *-3, 3. Henry knows that one expression can be selected from each of the columns below to form a correct simplification. Possibilities Possibilities Possibilities Code for A Code for B Code for C (x - 3) 4 (2x + 8) 7 (3x2 -27) 2 (2x - 6) 5 (x + 4) 8 (2x2 -18) 3 (3x -9) 6 2 ( x + 4 ) 9 (x2 -9) One possible selection to form a correct simplification is (x+3), (x+4) and (x2-9), so Henry records the code 159. To record another correct simplification, a code for another possibility is (record your answer as a three digit code abc). Certain expressions can be re-used
