Solution steps

- \frac{9}{2} - 8

Convert element to fraction:

8 = \frac{8 \cdot 2}{2}

= - \frac{8 \cdot 2}{2} - \frac{9}{2}

Since the denominators are equal, combine the fractions:

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

= \frac{- 8 \cdot 2 - 9}{2}

- 8 \cdot 2 - 9 = - 25

= \frac{- 25}{2}

Apply the fraction rule:

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

= - \frac{25}{2}

(x^{2} - x)^{2}

x^{2} (1 - \frac{2}{x})

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

l (e^{4 t} sin (t) - e^{2 t} cos (4 t))

\frac{6}{y} \cdot \frac{( x + y )}{4}
