## anonymous 2 years ago simplify the square root of x squared + 8x + 16

1. anonymous

You mean like this?$\sqrt{x^2+8x+16}$

2. AkashdeepDeb

$$x^2+8x+16$$ can be written in the form of a perfect square by using these identities: (a+b)^2 = a^2 + 2ab + b^2 (a-b)^2 = a^2 - 2ab + b^2 Try to factorize your expression, and you'll get the square root of it. Getting this? :)

@halorazer yeah
