tolong, yg jenius pasti bisa ini....

1. 3(4a-3) + 2(5a+6)
= 12a-9+10a+12
= 12a+10a-9+12
= 22a+3

2. 5(-2+4x) + 4(-8-3x)
= -10+20x-32-12x
= 20x-12x-10-32
= 8x-42

3. 2(-5p+3) + 4(-3+p)
= -10p+6-12+4p
= -10p+4p+6-12
= -6p-6

1) 3(4a-3) + 2(5a+6)
    = 12a - 9 + 10a + 12
    = 22a + 3

2) 5(-2+4x) + 4(-8-3x)
    = -10 + 20x - 24 - 12x
    = 8x - 34

3) 2(-5p+3) + 4(-3+p)
    = -10p + 6 - 12 + 4p
    = -6p - 6
