complete square (9x-3X^2)

9x-3x²

= -3(x² -3x)

= -3(x² - 2(3/2)x + (3/2)² - (3/2)² )

= -3(x² - 2(3/2)x + (3/2)²) + 27/4

= -3(x - 3/2)² + 27/4

==> 9x-3x² = 27/4 -3(x - 3/2)²

complete square (9x-3X^2)Solution9x-3x2 = -3(x2 -3x) = -3(x2 - 2(3/2)x + (3/2)2 - (3/2)2 ) = -3(x2 - 2(3/2)x + (3/2)2) + 27/4 = -3(x - 3/2)2 + 27/4 ==> 9x-3x
