3x^{2}\times 2=45000000
Multiply x and x to get x^{2}.
6x^{2}=45000000
Multiply 3 and 2 to get 6.
x^{2}=\frac{45000000}{6}
Divide both sides by 6.
x^{2}=7500000
Divide 45000000 by 6 to get 7500000.
x=500\sqrt{30} x=-500\sqrt{30}
Take the square root of both sides of the equation.
3x^{2}\times 2=45000000
Multiply x and x to get x^{2}.
6x^{2}=45000000
Multiply 3 and 2 to get 6.
6x^{2}-45000000=0
Subtract 45000000 from both sides.
x=\frac{0±\sqrt{0^{2}-4\times 6\left(-45000000\right)}}{2\times 6}
This equation is in standard form: ax^{2}+bx+c=0. Substitute 6 for a, 0 for b, and -45000000 for c in the quadratic formula, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.
x=\frac{0±\sqrt{-4\times 6\left(-45000000\right)}}{2\times 6}
Square 0.
x=\frac{0±\sqrt{-24\left(-45000000\right)}}{2\times 6}
Multiply -4 times 6.
x=\frac{0±\sqrt{1080000000}}{2\times 6}
Multiply -24 times -45000000.
x=\frac{0±6000\sqrt{30}}{2\times 6}
Take the square root of 1080000000.
x=\frac{0±6000\sqrt{30}}{12}
Multiply 2 times 6.
x=500\sqrt{30}
Now solve the equation x=\frac{0±6000\sqrt{30}}{12} when ± is plus.
x=-500\sqrt{30}
Now solve the equation x=\frac{0±6000\sqrt{30}}{12} when ± is minus.
x=500\sqrt{30} x=-500\sqrt{30}
The equation is now solved.
