(3x+2)(x-1)
= 3x²+3x+2x-2
= 3x²+5x-2
= c
2. (2p-3q)(5p+2q)
= 10p²+4pq-15pq-6q²
= 10p²-11pq-6q²
= c
3. (3p+7)(5-2p)
= 15p-6p²+35-14p
= 35+p-6p²
= a
= 3x kuadrat (-3x + 2x) - 2
= 3x kuadrat -x -2
jawabannya adalah B.
2. (2p - 3q) (5p + 2q)
= 10p kuadrat +(4pq - 15pq) - 6q kuadrat
= 10p kuadrat - 11pq - 6q kuadrat
jawabannya adalah C.
3. (3p + 7) (5 - 2p)
= 15p - 6p kuadrat + 35 - 14p
= 35 + p - 6p kuadrat
jawabannya adalah A.
