Ito ay isang quadratic equation, kailangan natin gumamit ng quadratic formula.

Ang quadratic formula ay:

       2a
* Alalahanin mo na ang isang quadratic equation ay ax²+bx+c=0

Kaya dito sa binigay mo,
x = 9 ± √(9²-4*12*5) = 9 ± √(81-240) = 9 ± √-159 = ± i√159
              2(12)                  24                  24             24
* Alalahanin mo na ang i ay katumbas ng √-1 ito ay imaginary dahil ito ay hindi rational.
