Answer:  \textsf{9x}^2\textsf{ - 12x + 4}

-------------------------------------------------------------------------------------------------------------

Given:  \textsf{(3x - 2)}^2

Find: \textsf{Simplify the expression}

Solution:  It looks like 2 is at the end of the parenthesis where the power would be instead of distributing the number.  If so the following steps would be followed.

<u>Expand</u>

  • \textsf{(3x - 2)}^2
  • \textsf{(3x - 2)(3x - 2)}
  • \textsf{(3x * 3x) + (3x * (-2)) + (3x * (-2)) + (-2 * (-2))}

<u>Simplify</u>

  • \textsf{9x}^2\textsf{ - 6x - 6x + 4}
  • \textsf{9x}^2\textsf{ - 12x + 4}

Therefore, after following the provided information we are able to determine that the expanded form would be 9x^2 - 12x + 4.
