To complete the square for an expression of the form \(\displaystyle{x}^{{2}}+{b}{x}\), you need to divide the value of b by 2 and then square the result.
Therefore, to complete the square for an expression of the form \(\displaystyle{x}^{{2}}+{b}{x}\), you need to add \(\displaystyle{\left(\frac{{b}}{{2}}\right)}^{{2}}\to{x}^{{2}}+{b}{x}.\)
