= x - 4

e x p an d \frac{( a d - ec - e x ) ( - a - x )}{e} + \frac{ab d ^{2}}{e ^{2}}

e x p an d \frac{4 x ( x + k )}{( 2 x + k ) ( k x + k ^{2} + 2 x )}

e x p an d (9 e f + 2 f) (e - 5)

e x p an d x - x H (x - 2) + 2 H (x \cdot 2)

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