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?

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6
