Solve y^2=52-48*(-08)

$$y ^ { 2 } = 52 - 48 \cdot ( - 08 )$$

Solve for y

$$y=2\sqrt{13}\approx 7.211102551$$

$$y=-2\sqrt{13}\approx -7.211102551$$

Steps by Finding Square Root

Multiply 48 and 0 to get 0.

$$y^{2}=52-0\times 8$$

Multiply 0 and 8 to get 0.

$$y^{2}=52-0$$

Subtract 0 from 52 to get 52.

$$y^{2}=52$$

Take the square root of both sides of the equation.

$$y=2\sqrt{13} y=-2\sqrt{13}$$

Steps Using the Quadratic Formula

Multiply 48 and 0 to get 0.

$$y^{2}=52-0\times 8$$

Multiply 0 and 8 to get 0.

$$y^{2}=52-0$$

Subtract 0 from 52 to get 52.

$$y^{2}=52$$

Subtract 52 from both sides.

$$y^{2}-52=0$$

This equation is in standard form: ax^{2}+bx+c=0. Substitute 1 for a, 0 for b, and -52 for c in the quadratic formula, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.

$$y=\frac{0±\sqrt{0^{2}-4\left(-52\right)}}{2}$$

Square 0.

$$y=\frac{0±\sqrt{-4\left(-52\right)}}{2}$$

Multiply -4 times -52.

$$y=\frac{0±\sqrt{208}}{2}$$

Take the square root of 208.

$$y=\frac{0±4\sqrt{13}}{2}$$

Now solve the equation y=\frac{0±4\sqrt{13}}{2} when ± is plus.

$$y=2\sqrt{13}$$

Now solve the equation y=\frac{0±4\sqrt{13}}{2} when ± is minus.

$$y=-2\sqrt{13}$$

The equation is now solved.

$$y=2\sqrt{13} y=-2\sqrt{13}$$
