Solve x^2=97

$${ x }^{ 2 } =97$$

Solve for x

$$x=\sqrt{97}\approx 9.848857802$$

$$x=-\sqrt{97}\approx -9.848857802$$

Steps by Finding Square Root

Take the square root of both sides of the equation.

$$x=\sqrt{97} x=-\sqrt{97}$$

Steps Using the Quadratic Formula

Subtract 97 from both sides.

$$x^{2}-97=0$$

This equation is in standard form: ax^{2}+bx+c=0. Substitute 1 for a, 0 for b, and -97 for c in the quadratic formula, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.

$$x=\frac{0±\sqrt{0^{2}-4\left(-97\right)}}{2}$$

Square 0.

$$x=\frac{0±\sqrt{-4\left(-97\right)}}{2}$$

Multiply -4 times -97.

$$x=\frac{0±\sqrt{388}}{2}$$

Take the square root of 388.

$$x=\frac{0±2\sqrt{97}}{2}$$

Now solve the equation x=\frac{0±2\sqrt{97}}{2} when ± is plus.

$$x=\sqrt{97}$$

Now solve the equation x=\frac{0±2\sqrt{97}}{2} when ± is minus.

$$x=-\sqrt{97}$$

The equation is now solved.

$$x=\sqrt{97} x=-\sqrt{97}$$
