x^{2}\times 37-348=0
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x^{2}.
x^{2}\times 37=348
Add 348 to both sides. Anything plus zero gives itself.
x^{2}=\frac{348}{37}
Divide both sides by 37.
x=\frac{2\sqrt{3219}}{37} x=-\frac{2\sqrt{3219}}{37}
Take the square root of both sides of the equation.
x^{2}\times 37-348=0
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x^{2}.
37x^{2}-348=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 37\left(-348\right)}}{2\times 37}
This equation is in standard form: ax^{2}+bx+c=0. Substitute 37 for a, 0 for b, and -348 for c in the quadratic formula, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.
x=\frac{0±\sqrt{-4\times 37\left(-348\right)}}{2\times 37}
Square 0.
x=\frac{0±\sqrt{-148\left(-348\right)}}{2\times 37}
Multiply -4 times 37.
x=\frac{0±\sqrt{51504}}{2\times 37}
Multiply -148 times -348.
x=\frac{0±4\sqrt{3219}}{2\times 37}
Take the square root of 51504.
x=\frac{0±4\sqrt{3219}}{74}
Multiply 2 times 37.
x=\frac{2\sqrt{3219}}{37}
Now solve the equation x=\frac{0±4\sqrt{3219}}{74} when ± is plus.
x=-\frac{2\sqrt{3219}}{37}
Now solve the equation x=\frac{0±4\sqrt{3219}}{74} when ± is minus.
x=\frac{2\sqrt{3219}}{37} x=-\frac{2\sqrt{3219}}{37}
The equation is now solved.
