6x^{2}+210=0
Multiply 35 and 6 to get 210.
6x^{2}=-210
Subtract 210 from both sides. Anything subtracted from zero gives its negation.
x^{2}=\frac{-210}{6}
Divide both sides by 6.
x^{2}=-35
Divide -210 by 6 to get -35.
x=\sqrt{35}i x=-\sqrt{35}i
The equation is now solved.
6x^{2}+210=0
Multiply 35 and 6 to get 210.
x=\frac{0±\sqrt{0^{2}-4\times 6\times 210}}{2\times 6}
This equation is in standard form: ax^{2}+bx+c=0. Substitute 6 for a, 0 for b, and 210 for c in the quadratic formula, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.
x=\frac{0±\sqrt{-4\times 6\times 210}}{2\times 6}
Square 0.
x=\frac{0±\sqrt{-24\times 210}}{2\times 6}
Multiply -4 times 6.
x=\frac{0±\sqrt{-5040}}{2\times 6}
Multiply -24 times 210.
x=\frac{0±12\sqrt{35}i}{2\times 6}
Take the square root of -5040.
x=\frac{0±12\sqrt{35}i}{12}
Multiply 2 times 6.
x=\sqrt{35}i
Now solve the equation x=\frac{0±12\sqrt{35}i}{12} when ± is plus.
x=-\sqrt{35}i
Now solve the equation x=\frac{0±12\sqrt{35}i}{12} when ± is minus.
x=\sqrt{35}i x=-\sqrt{35}i
The equation is now solved.
