It doesn't. If it were

(√x√(x + 1) + √(x + 1))/(√(x + 1)), then you would have

(√x√(x + 1) + √(x + 1))/(√(x + 1)) =

(√x√(x + 1) + 1√(x + 1))/(√(x + 1)) =

(√x + 1)(√(x + 1))/(√(x + 1)) =

√x + 1

Another way to show that it's wrong is to pick a value for x, say 3.

(√3√(3 + 1) + 1)/√(3 + 1) =

(√3√4 + 1)/√4 =

(√12 + 1)/√4 =

√12/2 + 1/2

but

√(3 + 1) =

2 so they're not equal

((√x*√(x + 1)) + 1) / (√(x + 1))

= √x + 1 / (√(x + 1))

It does not!

TYPO?

(I cannot see what it might be.)

Idk

Ok
