Recognize Equation Form: Recognize the quadratic equation and identify its standard form. A quadratic equation is in the form ax2+bx+c=0. Here, a=1, b=−2, and c=1.
Identify Perfect Square Trinomial: Look for a perfect square trinomial. The given quadratic equation x2−2x+1 resembles the square of a binomial because it follows the pattern a2−2ab+b2, which factors into (a−b)2.
Factor Using Binomial Pattern: Factor the quadratic equation using the square of a binomial pattern.The factors of x2−2x+1 are (x−1)(x−1) or (x−1)2, since (x−1)2=x2−2x+1.
