expand step(t-1)

Solution

expand

s t e p (t - 1)

Solution

es t^{2} p - es tp

Solution steps

s t e p (t - 1)

= es tp (t - 1)

Apply the distributive law:

a (b - c) = ab - a c

a = s t e p, b = t, c = 1

= s t e pt - s t e p \cdot 1

= es ttp - 1 es tp

Simplify

es ttp - 1 es tp : es t^{2} p - es tp

= es t^{2} p - es tp
