Solve (-2-(-1))^2+(2-1)^2:(-2)=

$$( - 2 - ( - 1 ) ) ^ { 2 } + ( 2 - 1 ) ^ { 2 } : ( - 2 ) =$$

Evaluate

$$\frac{1}{2}=0.5$$

Solution Steps

The opposite of -1 is 1.

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

Add -2 and 1 to get -1.

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

Calculate -1 to the power of 2 and get 1.

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

Subtract 1 from 2 to get 1.

$$1+\frac{1^{2}}{-2}$$

Calculate 1 to the power of 2 and get 1.

$$1+\frac{1}{-2}$$

Fraction \frac{1}{-2} can be rewritten as -\frac{1}{2} by extracting the negative sign.

$$1-\frac{1}{2}$$

Subtract \frac{1}{2} from 1 to get \frac{1}{2}.

$$\frac{1}{2}$$

Factor

$$\frac{1}{2} = 0.5$$
