x^{2}+2500=6.8^{2}
Calculate 50 to the power of 2 and get 2500.
x^{2}+2500=46.24
Calculate 6.8 to the power of 2 and get 46.24.
x^{2}=46.24-2500
Subtract 2500 from both sides.
x^{2}=-2453.76
Subtract 2500 from 46.24 to get -2453.76.
x=\frac{12\sqrt{426}i}{5} x=-\frac{12\sqrt{426}i}{5}
The equation is now solved.
x^{2}+2500=6.8^{2}
Calculate 50 to the power of 2 and get 2500.
x^{2}+2500=46.24
Calculate 6.8 to the power of 2 and get 46.24.
x^{2}+2500-46.24=0
Subtract 46.24 from both sides.
x^{2}+2453.76=0
Subtract 46.24 from 2500 to get 2453.76.
x=\frac{0±\sqrt{0^{2}-4\times 2453.76}}{2}
This equation is in standard form: ax^{2}+bx+c=0. Substitute 1 for a, 0 for b, and 2453.76 for c in the quadratic formula, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.
x=\frac{0±\sqrt{-4\times 2453.76}}{2}
Square 0.
x=\frac{0±\sqrt{-9815.04}}{2}
Multiply -4 times 2453.76.
x=\frac{0±\frac{24\sqrt{426}i}{5}}{2}
Take the square root of -9815.04.
x=\frac{12\sqrt{426}i}{5}
Now solve the equation x=\frac{0±\frac{24\sqrt{426}i}{5}}{2} when ± is plus.
x=-\frac{12\sqrt{426}i}{5}
Now solve the equation x=\frac{0±\frac{24\sqrt{426}i}{5}}{2} when ± is minus.
x=\frac{12\sqrt{426}i}{5} x=-\frac{12\sqrt{426}i}{5}
The equation is now solved.
