expand (1-L)*(1-t)

Solution

expand

(1 - L) \cdot (1 - t)

Solution

1 - t - L + L t

Solution steps

(1 - L) (1 - t)

Apply FOIL method:

(a + b) (c + d) = a c + a d + b c + b d

a = 1, b = - L, c = 1, d = - t

= 1 \cdot 1 + 1 \cdot (- t) + (- L) \cdot 1 + (- L) (- t)

Apply minus-plus rules

+ (- a) = - a, (- a) (- b) = ab

= 1 \cdot 1 - 1 \cdot t - 1 L + L t

Simplify

1 \cdot 1 - 1 \cdot t - 1 L + L t : 1 - t - L + L t

= 1 - t - L + L t
