Question

add.
$(3x^{2} + 6x + 2) + (3x + 1)$

Explanation:

Step1: Remove parentheses

To add the two polynomials, we first remove the parentheses. So we have \(3x^{2}+6x + 2+3x + 1\).

Step2: Combine like terms

Next, we combine the like terms. The \(x^{2}\) term is \(3x^{2}\). For the \(x\) terms, we have \(6x+3x = 9x\). For the constant terms, we have \(2 + 1=3\).
Putting it all together, we get \(3x^{2}+9x + 3\).

Answer:

\(3x^{2}+9x + 3\)
