Question

1.(2p-3q)(5p+2q=...?
2.3xy(x-2)(5x+1)=...?
3.(3p+7)(5-2p)=...?
4.(y+3)(y+4)=...?
5.(2y-3)(y-3)=...?

Answer 1

1.(2p-3q)(5p+2q=10p²+4pq-15pq-6q²
=10p²-11pq-6q²

2.3xy(x-2)(5x+1)=3xy(10x²+x-10x-2)
= 30x³y -27x²y -6xy

3.(3p+7)(5-2p)=15p-6p²+35-14p
= p-6p²+35
4.(y+3)(y+4)=y²+7y+12

5.(2y-3)(y-3)=2y²-9y+9
