\frac{17 + 129}{2}

Wende Bruchregel an:

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

\frac{17 + 129}{2} = \frac{17}{2} + \frac{129}{2}

= \frac{17}{2} + \frac{129}{2}

e x p an d - \frac{sin ( x )}{( x - π ) ( 1 - cos ( x ) )}

e x p an d \frac{11 s ^{2} - 4}{s ^{2} ( s ^{4} - 15 s ^{2} + 4 )}

e x p an d (67 - 55) (6 7 + 55)

e x p an d 8 - t^{2} (t + 3) (t + 1) (t - 1) (t - 5)

e x p an d (5 - t) (H ((t - 3) - H (t - 7)))
