Solve u=-(-1/2)^2-(-1/2)

$$u = - ( - \frac { 1 } { 2 } ) ^ { 2 } - ( - \frac { 1 } { 2 } )$$

Solve for u

$$u=\frac{1}{4}=0.25$$

Steps for Solving Linear Equation

Calculate -\frac{1}{2} to the power of 2 and get \frac{1}{4}.

$$u=-\frac{1}{4}-\left(-\frac{1}{2}\right)$$

The opposite of -\frac{1}{2} is \frac{1}{2}.

$$u=-\frac{1}{4}+\frac{1}{2}$$

Least common multiple of 4 and 2 is 4. Convert -\frac{1}{4} and \frac{1}{2} to fractions with denominator 4.

$$u=-\frac{1}{4}+\frac{2}{4}$$

Since -\frac{1}{4} and \frac{2}{4} have the same denominator, add them by adding their numerators.

$$u=\frac{-1+2}{4}$$

Add -1 and 2 to get 1.

$$u=\frac{1}{4}$$

Assign u

$$u≔\frac{1}{4}$$
