Complete the Square x^2-2x+

Problem

x2−2*x+…

Solution

1. Identify the coefficient of the linear term x which is b=−2

2. Divide the coefficient b by 2 to get b/2=(−2)/2=−1

3. Square the result of the division to find the constant needed to complete the square: (−1)2=1

4. Add this value to the expression to form a perfect square trinomial.

Final Answer

x2−2*x+1=(x−1)2
