A square has an area of x^2+4x+4 square meters. Write an expression that best represents the length of one side of the square.
Accepted Solution
A:
You have to find the square root of x^2+4x+4, which is: 1) Rewrite x^2+4x+4 as the square of a binomial: (x+2)^2 2) So now you know that (x+2)(x+2)=x^2+4x+4 (the area) 3) The length is x+2
