$$\frac { - 2 + \sqrt { ( 2 ) 2 - 4 ( - 1 ) ( - 1 ) } } { 2 ( - 1 ) }$$

Evaluate

$$1$$

Solution Steps

Multiply 2 and 2 to get 4.

$$\frac{-2+\sqrt{4-4\left(-1\right)\left(-1\right)}}{2\left(-1\right)}$$

Multiply 4 and -1 to get -4.

$$\frac{-2+\sqrt{4-\left(-4\left(-1\right)\right)}}{2\left(-1\right)}$$

Multiply -4 and -1 to get 4.

$$\frac{-2+\sqrt{4-4}}{2\left(-1\right)}$$

Subtract 4 from 4 to get 0.

$$\frac{-2+\sqrt{0}}{2\left(-1\right)}$$

Calculate the square root of 0 and get 0.

$$\frac{-2+0}{2\left(-1\right)}$$

Add -2 and 0 to get -2.

$$\frac{-2}{2\left(-1\right)}$$

Multiply 2 and -1 to get -2.

$$\frac{-2}{-2}$$

Divide -2 by -2 to get 1.

$$1$$

Factor

$$1$$
