Using the quadratic formula -
For an equation of the form ax^2+bx+c =0 , we know that
x = -b + sqrt (b^2 - 4ac)

-------------------------
2a
In the current case let us expand the equation, so we get
9x^2 + 12x+4 = 0
here a=9, b = 12 and c = 4
applying the values in the above quadratic formula for x we get,
x = -12+sqrt(144 - 144) OR x = -12+sqrt(144 - 144)

so x = -12/18 = -4/9

A slight fudge at the end: -12/18 is -2/3. (Greatest common divisor is 6.)
