Schritte zur Lösung

(2 + 1) (3 - 1)

Apply FOIL method

(2 + 1) (3 - 1) : 6 - 2 + 3 - 1

= 6 - 2 + 3 - 1

e x p an d \frac{s ^{2}}{( s - 1 ) ( s ^{3} - s ^{2} - 4 s + 4 )}

e x p an d x 2 - 30 x + c

e x p an d h^{2} (x + 1 + h + x + 1)

e x p an d \frac{- 10 x ^{2} + 240}{( x ^{2} + 4 ) ( x ^{2} + 144 )}

e x p an d, Va (\frac{8}{8 + 1}) (1 + \frac{10}{1.25})
