Adjust Fractions based on the LCM

= \frac{28}{21 x} - \frac{15 x}{21 x}

Apply the fraction rule:

\frac{a}{c} - \frac{b}{c} = \frac{a - b}{c}

= \frac{28 - 15 x}{21 x}

\frac{6 x ^{2} + x - 2}{9 x ^{2} - 4}

(z - 4)^{2}

4 x (3 x - 7) - 19 x^{2}

\frac{6}{3 x} + \frac{x + 5}{x ^{3}} + \frac{1 - 2 x ^{2}}{x ^{4}}

1 + \frac{i}{1 + \frac{i}{1 + \frac{i}{1 + i}}}
