Solve x^2=15div6/1

$${ x }^{ 2 } =15 \div \frac{ 6 }{ 1 }$$

Solve for x

$$x = \frac{\sqrt{10}}{2} \approx 1.58113883$$

$$x = -\frac{\sqrt{10}}{2} \approx -1.58113883$$

Steps by Finding Square Root

Divide 15 by \frac{6}{1} by multiplying 15 by the reciprocal of \frac{6}{1}.

$$x^{2}=\frac{15}{6}$$

Reduce the fraction \frac{15}{6} to lowest terms by extracting and canceling out 3.

$$x^{2}=\frac{5}{2}$$

Take the square root of both sides of the equation.

$$x=\frac{\sqrt{10}}{2} x=-\frac{\sqrt{10}}{2}$$

Steps Using the Quadratic Formula

Divide 15 by \frac{6}{1} by multiplying 15 by the reciprocal of \frac{6}{1}.

$$x^{2}=\frac{15}{6}$$

Reduce the fraction \frac{15}{6} to lowest terms by extracting and canceling out 3.

$$x^{2}=\frac{5}{2}$$

Subtract \frac{5}{2} from both sides.

$$x^{2}-\frac{5}{2}=0$$

This equation is in standard form: ax^{2}+bx+c=0. Substitute 1 for a, 0 for b, and -\frac{5}{2} for c in the quadratic formula, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.

$$x=\frac{0±\sqrt{0^{2}-4\left(-\frac{5}{2}\right)}}{2}$$

Square 0.

$$x=\frac{0±\sqrt{-4\left(-\frac{5}{2}\right)}}{2}$$

Multiply -4 times -\frac{5}{2}.

$$x=\frac{0±\sqrt{10}}{2}$$

Now solve the equation x=\frac{0±\sqrt{10}}{2} when ± is plus.

$$x=\frac{\sqrt{10}}{2}$$

Now solve the equation x=\frac{0±\sqrt{10}}{2} when ± is minus.

$$x=-\frac{\sqrt{10}}{2}$$

The equation is now solved.

$$x=\frac{\sqrt{10}}{2} x=-\frac{\sqrt{10}}{2}$$
