Sharina simplified the expression 3(2x – 6 – x + 1)2 – 2 + 4x. In Step 1 she simplified within the parentheses. In Step 2 she expanded the exponent. A table titled Sharina's Work with 1 column and 4 rows. The column is labeled 3(2 x minus 6 minus x + 1) squared minus 2 + 4 x. The first row has entry 3(x minus 5) squared minus 2 + 4 x. The second row has entry 3(x squared minus 10 x + 25) minus 2 + 4x. Rows 3 and 4 are blank.
