Solution
- The solution steps are given below:
[tex]\begin{gathered} x^2-6x+--- \\ \text{ To complete the square, we add the square of the half of the coeefficient of }x \\ \text{ That is, we add} \\ (-\frac{6}{2})^2=9 \\ \\ \text{ Thus, the perfect square is:} \\ x^2-6x+9 \end{gathered}[/tex]
Final Answer
The answer is
[tex]x^2-6x+9[/tex]
