Which of the following expressions is equivalent to (3x - 2)²?

A 9x² - 12x + 4

explanation

To square the expression (3x - 2)², we need to multiply it by itself. Using the FOIL method (First, Outer, Inner, Last), we can expand the expression:
(3x - 2)² = (3x - 2)(3x - 2)
= 9x² - 6x - 6x + 4
= 9x² - 12x + 4
Therefore, the expression (3x - 2)² is equivalent to 9x² - 12x + 4.
