Question

add.
$(8k^{2} + 2k) + (k + 5)$

Explanation:

Step1: Remove parentheses

To add the two polynomials, we first remove the parentheses. The expression becomes \(8k^{2}+2k + k + 5\).

Step2: Combine like terms

Next, we combine the like terms. The terms with \(k\) are \(2k\) and \(k\). Combining them gives \(2k + k=3k\). The term with \(k^{2}\) (\(8k^{2}\)) and the constant term (\(5\)) remain as they are. So the simplified expression is \(8k^{2}+3k + 5\).

Answer:

\(8k^{2}+3k + 5\)
