Question 131316: I've been multiplying polynomials however, the solution that I come up with for the product of these three, doesnt match the answer I was given. Could you please rectify my solution. Thank you.
(2y+1)(y+z)(3y-1)=(2y^2+2yz+y+z)(3y-1)
=6y^3+6y^2z+3y^2+3yz-2y^2-2yz-y-z
=6y^3+6y^2z+y^2+yz-y-z
The solution I was given was 6y^3+13y^2+y-z, which is correct?
