Part B: Correctly simplify this expression using a similar format - showing work for each step like was done above. Full credit will only be given if work shows Step 1, Step 2, Step 3, etc. as seen above.

Answer 1

Answer:

The first step is incorrect.  The correct answer is 44

Step-by-step explanation:

Only the (10-6) is being squared.  If the 2(10-6) was being squared, there would be another inclusion symbol [2(10-60]^2

2(10-6)^2 + 3 x 4

2($4^{2}$) + 3 x 4

2(16) + 3 x 4

32 + 12

44
