Answer 1

Given:

$(x+1)(4x^2+7x+6)$

Required:

To multiply the given polynomials.

Explanation:

Consider

$\begin{gathered} (x+1)(4x^2+7x+6) \\ \\ =4x^3+7x^2+6x+4x^2+7x+6 \\ \\ =4x^3+11x^2+13x+6 \end{gathered}$

Final Answer:

The option C is correct.

$\begin{equation*} 4x^3+11x^2+13x+6 \end{equation*}$
