Sederhanakan A. 4(3a + 2) B. (X + 3)(x - 2) C. (2x - 1)(x + 2y - 3)

a . 12a + 8
b . x²-2x +3x -6 = x² +1x -6
c.2x² + 4xy -6 -1x -2y +3

A. 4(3a+2)
= (4×3a) + (4×2)
= 12a + 8

B. (x+3) (x-2)
= x² - 2x + 3x - 6
= x² + x - 6

C. (2x -1) (x + 2y - 3)
= 2x² + 4xy - 6x - x - 2y + 3
= 2x² + 4xy - 7x - 2y +3

nb: maaf kalau salah^_^
