expand

1 - \frac{1}{2}

\frac{1}{2}

Solution steps

1 - \frac{1}{2}

Convert element to fraction:

1 = \frac{1 \cdot 2}{2}

= \frac{1 \cdot 2}{2} - \frac{1}{2}

Since the denominators are equal, combine the fractions:

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

= \frac{1 \cdot 2 - 1}{2}

1 \cdot 2 - 1 = 1

= \frac{1}{2}

\frac{- e ^{- x} x + e ^{- x}}{( x - 2 ) ^{2}}

(cos (t) + sin (t))^{4}

- \frac{1}{( s + 2 ) ( s + 1 ) ( s - 1 )}

\frac{\frac{d}{d x} ( x - 5 )}{( x + 2 ) ^{2}}

1 - cos (x) (1 - cos (x))
