1 –1 x –x = 0 x2 –x2 1 –1 x = 0 –x x2 –x2 = 0
Using Alge-Tiles, represent the following: 1) 2x + 3 2) 3a – 4 3) 5 – 4y
Adding like terms Example 1: (3x + 2) + 2x 3x + 2 + 2x = 5x + 2
Adding like terms Example 2: (5x + 3) + (x + 2) 5x + 3 + x + 2 = 6x + 5 5x + x + 3 + 2 (regroup)
Adding like terms Example 3: (4y + 3) + (2y – 6) 4y + 3 + 2y – 6 4y + 2y + 3 – 6 = regroup
Adding like terms Example 3: (4y + 3) + (2y – 6) 4y + 3 + 2y – 6 4y + 2y + 3 – 6 = regroup 2y – 3
Adding like terms Example 4: (3z – 2) + (3z + 5) 3z – 2 + 3z + 5 regroup 3z + 3z – 2 + 5
Adding like terms Example 4: (3z – 2) + (3z + 5) 3z – 2 + 3z + 5 regroup 3z + 3z – 2 + 5 = 6z + 3
