Simplify square root of x^2+8x+16

Problem

√(,x^2+8*x+16)

Solution

1. Identify the expression inside the square root as a quadratic trinomial of the form a*x^2+b*x+c

2. Recognize that the radicand x^2+8*x+16 is a perfect square trinomial because it follows the pattern a^2+2*a*b+b^2 where a=x and b=4

3. Factor the quadratic expression into its squared binomial form.

x^2+8*x+16=(x+4)^2

4. Apply the property of square roots √(,u^2)=|u| to simplify the expression.

√(,(x+4)^2)=|x+4|

Final Answer

√(,x^2+8*x+16)=|x+4|
