Solve z/4+2/a_{1}

$$\frac { z } { 4 } + \frac { 2 } { a _ { 1 } }$$

Evaluate

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

Short Solution Steps

To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 4 and a_{1} is 4a_{1}. Multiply \frac{z}{4} times \frac{a_{1}}{a_{1}}. Multiply \frac{2}{a_{1}} times \frac{4}{4}.

$$\frac{za_{1}}{4a_{1}}+\frac{2\times 4}{4a_{1}}$$

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

$$\frac{za_{1}+2\times 4}{4a_{1}}$$

Do the multiplications in za_{1}+2\times 4.

$$\frac{za_{1}+8}{4a_{1}}$$

Factor

$$\frac{z+\frac{8}{a_{1}}}{4}$$
