A = -2(3x - 2y) - 5(2y - 3x) = -2(3x - 2y) + 5(3x - 2y)

= 3(3x - 2y) = 9x - 6y

B = (4x² - 3y)2y - (3x² - 4y)3y = 8x²y - 6y² - 9x²y + 12y²

= 6y² - x²y

We have:

A = -2 (3x - 2y) - 5 (2y - 3x) = -2 (3x - 2y) + 5 (3x - 2y)

= 3 (3x - 2y) = 9x - 6y

B = (4x²- 3y) . 2y - (3x² - 4y) . 3y = 8x² . y - 6y² 9x² . y + 12y²

= 6y² - x². y
