8=-24xx
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
8=-24x^{2}
Multiply x and x to get x^{2}.
-24x^{2}=8
Swap sides so that all variable terms are on the left hand side.
x^{2}=\frac{8}{-24}
Divide both sides by -24.
x^{2}=-\frac{1}{3}
Reduce the fraction \frac{8}{-24} to lowest terms by extracting and canceling out 8.
x=\frac{\sqrt{3}i}{3} x=-\frac{\sqrt{3}i}{3}
The equation is now solved.
8=-24xx
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
8=-24x^{2}
Multiply x and x to get x^{2}.
-24x^{2}=8
Swap sides so that all variable terms are on the left hand side.
-24x^{2}-8=0
Subtract 8 from both sides.
x=\frac{0±\sqrt{0^{2}-4\left(-24\right)\left(-8\right)}}{2\left(-24\right)}
This equation is in standard form: ax^{2}+bx+c=0. Substitute -24 for a, 0 for b, and -8 for c in the quadratic formula, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.
x=\frac{0±\sqrt{-4\left(-24\right)\left(-8\right)}}{2\left(-24\right)}
Square 0.
x=\frac{0±\sqrt{96\left(-8\right)}}{2\left(-24\right)}
Multiply -4 times -24.
x=\frac{0±\sqrt{-768}}{2\left(-24\right)}
Multiply 96 times -8.
x=\frac{0±16\sqrt{3}i}{2\left(-24\right)}
Take the square root of -768.
x=\frac{0±16\sqrt{3}i}{-48}
Multiply 2 times -24.
x=-\frac{\sqrt{3}i}{3}
Now solve the equation x=\frac{0±16\sqrt{3}i}{-48} when ± is plus.
x=\frac{\sqrt{3}i}{3}
Now solve the equation x=\frac{0±16\sqrt{3}i}{-48} when ± is minus.
x=-\frac{\sqrt{3}i}{3} x=\frac{\sqrt{3}i}{3}
The equation is now solved.
