expand L(t-2)u(t)

Solution

expand

L (t - 2) u (t)

Solution

L t^{2} u - 2 L t u

Solution steps

L (t - 2) u (t)

= L (t) u (t - 2)

Apply the distributive law:

a (b - c) = ab - a c

a = Lu (t), b = t, c = 2

= Lu (t) t - Lu (t) \cdot 2

= L (t) t u - 2 L (t) u

Simplify

L (t) t u - 2 L (t) u : L t^{2} u - 2 L t u

= L t^{2} u - 2 L t u
