Question

MULTIPLY:

i) (3x-5y+7z) by - 3xyz

ii) (2p²-3pq+5q²+5) by -2pq​

Answer 1

Answer:

i) $-9x^{2} yz+15xy^{2} z-21xyz^{2}$

ii)$-4p^{3} q+6p^{2} q^{2} -10pq^{3} -10pq$

Step-by-step explanation:

i) (3x-5y+7z)(-3xyz)

=-9x^2yz+15xy^2z-21xyz^2

ii) (-2pq)(2p^2-3pq+5q^2+5)

=-4p^3q+6p^2q^2-10pq^3-10pq
