Simplify by finding the product of the polynomials below. Then Identify the degree of your answer. When typing your answer use t
nexus9112 [7]

Solution:

Given:

(2x^2+2x+1)(4x-1)

To get the product of the polynomial; we use the distributive property of multiplication.

a(b+c)=ab+ac

\begin{gathered} (4x-1)(2x^2+2x+1) \\ 4x(2x^2+2x+1)-1(2x^2+2x+1) \\ =8x^3+8x^2+4x-2x^2-2x-1 \\ \text{Collecting similar terms together and simplifying further;} \\ =8x^3+8x^2-2x^2+4x-2x-1 \\ =8x^3+6x^2+2x-1 \end{gathered}

Therefore, the product of the polynomials is;

8x^3+6x^2+2x-1
