expand (x+1)(x+1)!

Solution

expand

(x + 1) (x + 1)!

Solution

x (x + 1)! + (x + 1)!

Solution steps

(x + 1) (x + 1)!

= (x + 1)! (x + 1)

Apply the distributive law:

a (b + c) = ab + a c

a = (x + 1)!, b = x, c = 1

= (x + 1)! x + (x + 1)! \cdot 1

= x (x + 1)! + 1 \cdot (x + 1)!

Multiply:

1 \cdot (x + 1)! = (x + 1)!

= x (x + 1)! + (x + 1)!
