Identify Like Terms: Identify the like terms in both polynomials. The like terms are the terms that have the same variable raised to the same power. In the given polynomials, the like terms are the terms with $k^2$ , the terms with $k$ , and the constant terms.
Add Coefficients of $k^2$ : Add the coefficients of the like terms with $k^2$ .
$(9k^2 + 7k + 6) + (9k^2 + 5k + 4)$
= $(9k^2 + 9k^2) + (7k + 5k) + (6 + 4)$
= $18k^2 + (7k + 5k) + (6 + 4)$
Add Coefficients of $k$ : Add the coefficients of the like terms with $k$ . $\newline$ $18k^2 + (7k + 5k) + (6 + 4)$ $\newline$ = $18k^2 + 12k + (6 + 4)$
Add Constant Terms: Add the constant terms. $\newline$ $18k^2 + 12k + (6 + 4) = 18k^2 + 12k + 10$
Write Final Expression: Write the final simplified expression. $\newline$ The sum of the polynomials is $18k^2 + 12k + 10$ .
