Adjust Fractions based on the LCM

= \frac{14}{35} - \frac{15}{35}

Apply the fraction rule:

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

= \frac{14 - 15}{35}

14 - 15 = - 1

= \frac{- 1}{35}

Apply the fraction rule:

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

= - \frac{1}{35}

\frac{2}{5} - \frac{3}{2}

(a^{2} b^{- 2})^{- 3} (a^{3})^{- 2}

2 x 3

(1 + 5)^{3}

3 x^{2} + 5 + 4 x - 2 - x^{2} - 3 x + 1
