Answer:

x = 3 ±
(√(10) )/(-2)

Explanation:

To find the roots of this equation, we can either use facotring or the quadratic formula. Because this equation isn't facotrable, we will use the quadratic formula to solve it

-2
x^2 + 12x - 13 = 0

x =
(-12 +- √(12^2 - 4(-13)(-2)) )/(-4)

x =
(-12 +- √(144-104) )/(-4)

x =
-(-12 +- √(40) )/(-4)

x = 3 ±
(√(10) )/(-2)
