Solve 145*00=I*600*220quadI=

$$145 \times 00 = I \times 600 \times 220 \quad I =$$

Solve for I

$$I=0$$

Steps by Finding Square Root

Multiply I and I to get I^{2}.

$$145\times 0\times 0=I^{2}\times 600\times 220$$

Multiply 145 and 0 to get 0.

$$0\times 0=I^{2}\times 600\times 220$$

Multiply 0 and 0 to get 0.

$$0=I^{2}\times 600\times 220$$

Multiply 600 and 220 to get 132000.

$$0=I^{2}\times 132000$$

Swap sides so that all variable terms are on the left hand side.

$$I^{2}\times 132000=0$$

Divide both sides by 132000. Zero divided by any non-zero number gives zero.

$$I^{2}=0$$

Take the square root of both sides of the equation.

$$I=0 I=0$$

The equation is now solved. Solutions are the same.

$$I=0$$

Steps Using the Quadratic Formula

Multiply I and I to get I^{2}.

$$145\times 0\times 0=I^{2}\times 600\times 220$$

Multiply 145 and 0 to get 0.

$$0\times 0=I^{2}\times 600\times 220$$

Multiply 0 and 0 to get 0.

$$0=I^{2}\times 600\times 220$$

Multiply 600 and 220 to get 132000.

$$0=I^{2}\times 132000$$

Swap sides so that all variable terms are on the left hand side.

$$I^{2}\times 132000=0$$

Divide both sides by 132000. Zero divided by any non-zero number gives zero.

$$I^{2}=0$$

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

$$I=\frac{0±\sqrt{0^{2}}}{2}$$

Take the square root of 0^{2}.

$$I=\frac{0±0}{2}$$

Divide 0 by 2.

$$I=0$$
