Question

Using the distributive property to find the product (y – 4)(y2 + 4y + 16) results in a polynomial of the form y3 + 4y2 + ay – 4y2 – ay – 64. What is the value of a in the polynomial?

Answer 1

distributive property says
\[(A+B)(C+D+\cdots)\\=A(C+D+\cdots)+B(C+D+\cdots)\\
=(AC+AD+A\cdots)+(BC+BD+B\cdots)\]

Answer 2

???
whats the answer

Answer 3

(y – 4) (y^2 + 4y + 16)
= y (y^2 + 4y + 16) - 4 (y^2 + 4y + 16)
=
