expand-1/4 (1-s)(1-t)+(-1/4)(1+s)(1-t)

expand

- \frac{1}{4} (1 - s) (1 - t) + (- \frac{1}{4}) (1 + s) (1 - t)

\frac{t - 1}{2}

Solution steps

- \frac{1}{4} (1 - s) (1 - t) + (- \frac{1}{4}) (1 + s) (1 - t)

Simplify

(- \frac{1}{4}) (1 + s) (1 - t) : - \frac{1}{4} (1 + s) (1 - t)

= - \frac{1}{4} (1 - s) (1 - t) - \frac{1}{4} (1 + s) (1 - t)

Expand

- \frac{1}{4} (1 - s) (1 - t) : \frac{- 1 + t + s - s t}{4}

= \frac{- 1 + t + s - s t}{4} - \frac{1}{4} (1 + s) (1 - t)

Expand

- \frac{1}{4} (1 + s) (1 - t) : \frac{- 1 + t - s + s t}{4}

= \frac{- 1 + t + s - s t}{4} + \frac{- 1 + t - s + s t}{4}

Join

\frac{- 1 + t + s - s t}{4} + \frac{- 1 + t - s + s t}{4} : \frac{t - 1}{2}

= \frac{t - 1}{2}

\frac{15}{( x + 2 ) ^{2}}

(x - a) \cdot (x - \frac{a + 2 b}{3}) \cdot (x - b)

\frac{3}{4} (x - 4 = - \frac{1}{4} (x - 16))

- \frac{1}{4} (- cos (8 x^{4}) + 1)

(- 1 - i 3) (- 1 + i 3)^{'} (x - 2)^{'}
