2400000m^{2}=2400
Multiply m and m to get m^{2}.
m^{2}=\frac{2400}{2400000}
Divide both sides by 2400000.
m^{2}=\frac{1}{1000}
Reduce the fraction \frac{2400}{2400000} to lowest terms by extracting and canceling out 2400.
m=\frac{\sqrt{10}}{100} m=-\frac{\sqrt{10}}{100}
Take the square root of both sides of the equation.
2400000m^{2}=2400
Multiply m and m to get m^{2}.
2400000m^{2}-2400=0
Subtract 2400 from both sides.
m=\frac{0±\sqrt{0^{2}-4\times 2400000\left(-2400\right)}}{2\times 2400000}
This equation is in standard form: ax^{2}+bx+c=0. Substitute 2400000 for a, 0 for b, and -2400 for c in the quadratic formula, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.
m=\frac{0±\sqrt{-4\times 2400000\left(-2400\right)}}{2\times 2400000}
Square 0.
m=\frac{0±\sqrt{-9600000\left(-2400\right)}}{2\times 2400000}
Multiply -4 times 2400000.
m=\frac{0±\sqrt{23040000000}}{2\times 2400000}
Multiply -9600000 times -2400.
m=\frac{0±48000\sqrt{10}}{2\times 2400000}
Take the square root of 23040000000.
m=\frac{0±48000\sqrt{10}}{4800000}
Multiply 2 times 2400000.
m=\frac{\sqrt{10}}{100}
Now solve the equation m=\frac{0±48000\sqrt{10}}{4800000} when ± is plus.
m=-\frac{\sqrt{10}}{100}
Now solve the equation m=\frac{0±48000\sqrt{10}}{4800000} when ± is minus.
m=\frac{\sqrt{10}}{100} m=-\frac{\sqrt{10}}{100}
The equation is now solved.
