Tentuka hasil perkalian dari 1. (3x+2) (x-I) 2. (Y+5) (y+3) 3. (3p+7) (5-2p)

1. (3x+2)(x-1)
3x²-3x+2x-2
3x² -x -2

2. (y+5)(y+3)
y² +3y +5y +15
y² +8y +15

3. (3p+7)(5-2p)
(3p+7)(-2p+5)
-6p² +15p -14p +12
-6p² +p +12

1.(3x+2)(x-1)= (3x^2-3+2x-2)
= (3x^2-x-2)

2. (y+5)(y+3)
= (y^2+3y+5y+15)
=y^2+8y+15)

3.(3p+7)(5-2p)
=(6p^2-15p+14p+35)
=(6p^2-P+35)
