3x+4y-8x+2y
= 3x -8x + 2y + 4y
= -5x +6y
2.
(6a²-12a) + (3a² -5a+8)
= 6a² -12a + 3a² - 5a + 8
= 6a² + 3a² - 12a - 5a + 8
= 9a² - 17a + 8
3.
A= -2x + 3y
= 3(-2x+3y)
3A = -6x + 9y
B = 2x + 3y
= 2(2x+3y)
2B = 4x + 6y
maka 2B - 3A :
(4x+6y) - (-6x+9y)
= 4x+6y +6x -9y
= 4x +6x +6y-9y
= 10x -3y
4)
(3x+2y) (9x-6y)
= 27x² - 18xy + 18xy - 12y²
= 27x² - 12y²
