Question

How do you perform the indicated operation?(4y + 11)(3y² -2y -7)

Answer 1

`(4y+11)(3y^2-2y-7)`

we use distributive property

`(4y*3y^2)+(4y*-2y)+(4y*-7)+(11*3y^2)+(11*-2y)+(11*-7)`
`\begin{gathered} (12y^3)+(-8y^2)+(-28y)+(33y^2)+(-22y)+(-77) \\ 12y^3-8y^2+33y^2-28y-22y-77 \\ 12y^3+25y^2-50y-77 \end{gathered}`
