You can wrirte 4 as .

Write your expression as a single fraction once they're over a common denominator (x+1)^2.

Expand your numerator, and refactorise once you've included the -1 in your numerator.

The denominator is square rooted to remove the squared power, while the numerator is left to the power 1/2 (which is equivilent to square root)
