Solve 2+y^2/15

$$2 + \frac { y ^ { 2 } } { 15 }$$

Evaluate

$$\frac{y^{2}}{15}+2$$

Short Solution Steps

To add or subtract expressions, expand them to make their denominators the same. Multiply 2 times \frac{15}{15}.

$$\frac{2\times 15}{15}+\frac{y^{2}}{15}$$

Since \frac{2\times 15}{15} and \frac{y^{2}}{15} have the same denominator, add them by adding their numerators.

$$\frac{2\times 15+y^{2}}{15}$$

Do the multiplications in 2\times 15+y^{2}.

$$\frac{30+y^{2}}{15}$$

Factor

$$\frac{y^{2}+30}{15}$$

Solution Steps

Factor out \frac{1}{15}. Polynomial 30+y^{2} is not factored since it does not have any rational roots.

$$\frac{30+y^{2}}{15}$$
