Solve (7/7*1/2)^2-(-1/2)^2=

$$( \frac { 7 } { 7 } \cdot \frac { 1 } { 2 } ) ^ { 2 } - ( - \frac { 1 } { 2 } ) ^ { 2 } =$$

Evaluate

$$0$$

Solution Steps

Divide 7 by 7 to get 1.

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

Multiply 1 and \frac{1}{2} to get \frac{1}{2}.

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

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

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

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

$$\frac{1}{4}-\frac{1}{4}$$

Subtract \frac{1}{4} from \frac{1}{4} to get 0.

$$0$$

Factor

$$0$$
