Jeremy's solution to a problem involving polynomial expressions is

shown below.

Step 1: a(2a + 7b) - b(9 + 5a2 - 4a) +662

Step 2: 2a + 7ab - b(9 +5a- 4a) + 662

Step 3: 2a + 7ab - 96 + 5a2b-4ab +662

Step 4: 7a²b + 3ab - 96 +662

What mistakes, if any, did Jeremy

make and in which steps were the

errors first made?
