what is the intermediate step in the form (x+a)^2=b as a result of completing the square for the following equation?Answer( )^2=

Solution
For this case we have the following equation:
[tex]x^2+2x=319[/tex]If we complete the square we got this:
[tex]x^2+2x+1=319+1[/tex]Then after simplify we got:
[tex](x+1)^2=320[/tex]
