Factor x^2-4x+4

Problem

x2−4*x+4

Solution

1. Identify the structure of the quadratic expression, which is in the form a*x2+b*x+c where a=1 b=−4 and c=4

2. Recognize that the expression is a perfect square trinomial because the first term is x2 the last term is 2 and the middle term is −2*(x)*(2)

3. Apply the formula for a perfect square trinomial, a2−2*a*b+b2=(a−b)2

4. Substitute a=x and b=2 into the formula to get (x−2)2

Final Answer

x2−4*x+4=(x−2)2
