展开

(\frac{5}{6} x + \frac{4}{5}) (\frac{1}{2} x + \frac{5}{2})

\frac{5 x ^{2}}{12} + \frac{149 x}{60} + 2

求解步骤

(\frac{5}{6} x + \frac{4}{5}) (\frac{1}{2} x + \frac{5}{2})

Apply FOIL method

(\frac{5}{6} x + \frac{4}{5}) (\frac{1}{2} x + \frac{5}{2}) : \frac{5 x ^{2}}{12} + \frac{149 x}{60} + 2

= \frac{5 x ^{2}}{12} + \frac{149 x}{60} + 2

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

e x p an d \frac{11 x + 6}{( 2 x + 3 ) ^{2} ( x + 5 )}

e x p an d (A = - 1 + \frac{π}{16} + \frac{1}{32} sin (\frac{8 π}{45})) 8

s im pl i f y (16 + 8 x - 36)^{2}

e x p an d \frac{s ^{3} + 5 s ^{2} + 5 s + 20}{( s ^{2} + 4 ) ( s + 1 ) ( s + 4 )}
