248832+x^{2}=0
Calculate 12 to the power of 5 and get 248832.
x^{2}=-248832
Subtract 248832 from both sides. Anything subtracted from zero gives its negation.
x=288\sqrt{3}i x=-288\sqrt{3}i
The equation is now solved.
248832+x^{2}=0
Calculate 12 to the power of 5 and get 248832.
x^{2}+248832=0
Quadratic equations like this one, with an x^{2} term but no x term, can still be solved using the quadratic formula, \frac{-b±\sqrt{b^{2}-4ac}}{2a}, once they are put in standard form: ax^{2}+bx+c=0.
x=\frac{0±\sqrt{0^{2}-4\times 248832}}{2}
This equation is in standard form: ax^{2}+bx+c=0. Substitute 1 for a, 0 for b, and 248832 for c in the quadratic formula, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.
x=\frac{0±\sqrt{-4\times 248832}}{2}
Square 0.
x=\frac{0±\sqrt{-995328}}{2}
Multiply -4 times 248832.
x=\frac{0±576\sqrt{3}i}{2}
Take the square root of -995328.
x=288\sqrt{3}i
Now solve the equation x=\frac{0±576\sqrt{3}i}{2} when ± is plus.
x=-288\sqrt{3}i
Now solve the equation x=\frac{0±576\sqrt{3}i}{2} when ± is minus.
x=288\sqrt{3}i x=-288\sqrt{3}i
The equation is now solved.
