x=\frac{6+\sqrt{36-4\times 1\left(-27\right)}}{2}
Calculate -6 to the power of 2 and get 36.
x=\frac{6+\sqrt{36-4\left(-27\right)}}{2}
Multiply 4 and 1 to get 4.
x=\frac{6+\sqrt{36-\left(-108\right)}}{2}
Multiply 4 and -27 to get -108.
x=\frac{6+\sqrt{36+108}}{2}
The opposite of -108 is 108.
x=\frac{6+\sqrt{144}}{2}
Add 36 and 108 to get 144.
x=\frac{6+12}{2}
Calculate the square root of 144 and get 12.
x=\frac{18}{2}
Add 6 and 12 to get 18.
x=9
Divide 18 by 2 to get 9.
