Adjust Fractions based on the LCM

= \frac{45}{35} - \frac{56}{35}

Apply the fraction rule:

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

= \frac{45 - 56}{35}

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

= - \frac{11}{35}

\frac{9}{8 x} + \frac{5}{4 x}

a^{3} (a - b + 1) - b^{2} (a - b + 1)

(x^{2} + 3 x + 2)^{2}

x^{4} - 7 x^{2} - 8

\frac{1}{2} x + x
