Solve 2(-1)^2/(-1)^2+(+1)+4

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

Evaluate

$$\frac{1}{3}\approx 0.333333333$$

Solution Steps

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

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

Multiply 2 and 1 to get 2.

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

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

$$\frac{2}{1+1+4}$$

Add 1 and 1 to get 2.

$$\frac{2}{2+4}$$

Add 2 and 4 to get 6.

$$\frac{2}{6}$$

Reduce the fraction \frac{2}{6} to lowest terms by extracting and canceling out 2.

$$\frac{1}{3}$$

Factor

$$\frac{1}{3} = 0.3333333333333333$$
