Factor. 2s^2 + 9s + 7 ____

Identify coefficients: Identify the coefficients a, b, and c in the quadratic expression 2s^2 + 9s + 7 by comparing it to the standard form ax^2 + bx + c. a = 2, b = 9, c = 7.Find two numbers: Find two numbers that multiply to a*c (2*7 = 14) and add up to b (9). The numbers that satisfy these conditions are 2 and 7 because 2*7 = 14 and 2+7 = 9.Rewrite middle term: Rewrite the middle term 9s using the two numbers found in the previous step. 2s^2 + 9s + 7 can be rewritten as 2s^2 + 2s + 7s + 7.Factor by grouping: Factor by grouping. Group the first two terms together and the last two terms together. (2s^2 + 2s) + (7s + 7).Factor out common factor: Factor out the greatest common factor from each group. 2s(s + 1) + 7(s + 1).Final factored form: Since both groups contain the common factor (s + 1), factor this out. (2s + 7)(s + 1) is the factored form of the quadratic expression.

2s^2 + 9s + 7

Identify coefficients: Identify the coefficients $a$ , $b$ , and $c$ in the quadratic expression $2s^2 + 9s + 7$ by comparing it to the standard form $ax^2 + bx + c$ . $a = 2$ , $b = 9$ , $c = 7$ .
Find two numbers: Find two numbers that multiply to $a*c$ ( $2*7 = 14$ ) and add up to $b$ ( $9$ ). $\newline$ The numbers that satisfy these conditions are $2$ and $7$ because $2*7 = 14$ and $2+7 = 9$ .
Rewrite middle term: Rewrite the middle term $9s$ using the two numbers found in the previous step. $2s^2 + 9s + 7$ can be rewritten as $2s^2 + 2s + 7s + 7$ .
Factor by grouping: Factor by grouping. Group the first two terms together and the last two terms together. $2s^2 + 2s$ + $7s + 7$ .
Factor out common factor: Factor out the greatest common factor from each group. $2s(s + 1) + 7(s + 1)$ .
Final factored form: Since both groups contain the common factor $(s + 1)$ , factor this out. $(2s + 7)(s + 1)$ is the factored form of the quadratic expression.
