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. which is a possible next step? a. simplify the expression by adding and subtracting from left to right. b. combine like terms within the parentheses. c. combine all x-terms. d. distribute the 3 to each term in the parentheses by multiplying.

d. distribute the 3 to each term in the parentheses by multiplying.

Watch:

Beginning 3(2x - 6 - x - 1)^2 - 2 + 4x

Step 1: simplify within the parentheses: 3(x-7)^2 - 2 + 4x

Step 2: Expand the exponent: 3 (x^2 -14x +49) - 2 + 4x

Step 3: distribute 3 to each term in the parentheses by multiplying

3x^2 - 42x + 147 - 2 + 4x

Step 4: you can do it.

The next step is to combine like terms within the parentheses

How to determine the possible next step?

The expression is given as:

3(2x - 6 - x + 1)^2 - 2 + 4x

Step 1: Simplify the expressions in the parenthesis.

3(x - 5)^2 - 2 + 4x

Step 2: Expand the exponent

3(x^2 - 5x - 5x + 25) - 2 + 4x

At this point, the next step is to combine like terms within the parentheses

This gives

3(x^2 -10x + 25) - 2 + 4x

Hence, the next step is to combine like terms within the parentheses
