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. Which is a possible next step? Simplify the expression by adding and subtracting from left to right. Combine like terms within the parentheses. Combine all x-terms. Distribute the 3 to each term in the parentheses by multiplying.
