expand (1-a)*(1-b)left(1-c)

expand

(1 - a) \cdot (1 - b) l e f t (1 - c)

e l f t - e l f t c - e l b f t + e l b f t c - e a l f t + e a l f t c + e a l b f t - e a l b f t c

Solution steps

(1 - a) (1 - b) l e f t (1 - c)

= e l f t (1 - a) (1 - b) (1 - c)

Expand

(1 - a) (1 - b) : 1 - b - a + ab

= l e f t (1 - b - a + ab) (1 - c)

Expand

(1 - b - a + ab) (1 - c) : 1 - c - b + b c - a + a c + ab - ab c

= l e f t (1 - c - b + b c - a + a c + ab - ab c)

Expand

l e f t (1 - c - b + b c - a + a c + ab - ab c) : e l f t - e l f t c - e l b f t + e l b f t c - e a l f t + e a l f t c + e a l b f t - e a l b f t c

= e l f t - e l f t c - e l b f t + e l b f t c - e a l f t + e a l f t c + e a l b f t - e a l b f t c

(e^{- a s} - 1)^{2}
