Recall that the quadratic formula states that the solutions to the equation:


ax^2+bx+c=0

are:


x=(-b\pm√(b^2-4ac))/(2a).

Therefore the solutions to the given equation are:


x=(-(-1)\pm√((-1)^2-4(6)(-12)))/(2(6)).

Simplifying the above result we get:


x=(1\pm√(1+288))/(12)=(1\pm√(289))/(12)=(1\pm14)/(12).

Then the solutions to the given equation are:


x=(1-14)/(12)=-(13)/(12)\text{ and x=}(1+14)/(12)=(15)/(12)=(5)/(4).

Answer:


x=-(13)/(12)\text{ and }x=(5)/(4).
