Use the quadratic equation: x = (-b plusminus root(b2 - 4ac)) / 2a
In this case, a = 1, b = 9, c = 12.
Another answer:
x2+9x+12 = 0
When factorised by means of the quadratic equation formula:
(x+7.372281323)(x+1.627718677) = 0
Therefore the roots are: -7.372281323 and -1.627718677
Check that your answer is correct by multiplying out the brackets which should bring you back to x2+9x+12 = 0
