You can put this solution on YOUR website!
a. 3y^2 (-7y^2 + 3y –6)[Multiply using the distributive property]
%28-21y%5E4+%2B9y%5E3+-18y%5E2%29
.
b. (3y –2 ) ( 4y^2 + 3y –5 ) [Use the FOIL method to multiply]
%2812y%5E3+%2B+9y%5E2+-+15y+-8y%5E2+-6y+%2B10%29
%2812y%5E3+%2B+y%5E2+-+21y+%2B10%29 [Combine like-terms]
