Solving by factoring n^2+9n=-14

(n + 7)(n + 2) = 0

Step-by-step explanation:

Set the equation equal to 0. Add 14 to both sides:

n² + 9n = -14

n² + 9n (+14) = -14 (+14)

n² + 9n + 14 = 0

Find factors of 14 & n, that, when combined, will equal 9n.

n² + 9n + 14 = 0

n               7

n               2

(n + 7)(n + 2) = 0

(n + 7)(n + 2) = 0 is your answer.
