- (a)3x2yz2 – 3xy2z + x2yz2 + 7xy2z
- (b)x4 + 3x3y + 3x2y2 – 3x3y – 3xy3 + y4 – 3x2y2
- (c)p3q2r + pq2r3 + 3p2qr2 – 9p2qr2
- (d)2a + 2b + 2c – 2a – 2b – 2c – 2b + 2c + 2a (e) 50x3 – 21x + 107 + 41x3 – x + 1 – 93 + 71x – 31x3 15-04-2018 Four sequences of patterns start as shown below: The four patterns are different. 1. What do the four patterns have in common? You may continue the sequence of each pattern as far as you want. 2. How many squares, dots, stars or bars will the 10th figure of each sequence have? 15-04-2018
