Question

Solve each equation by factoring ! NEED THIS IN 5 MIN ILL GIVE YOU BRAINLIEST!

Answer 1

for problem 6, you will want to subtract both sides by 5.

n^2 + 7n + 10 = 0

then factor:

(n + 5) (n + 2) = 0

n+ 5 = 0, n +2 = 0

n = -5, n = -2

----------------------------

for problem 7, add - 12 and - 6 together

n^2 + 3n - 18

(you can put = 0 next to the equation since that can make it easier to solve, I guess)

n^2 + 3n - 18 = 0

then factor:

(n + 6) (n - 3) = 0

n + 6 = 0, n - 3 = 0

n = -6, n = 3
