Factor x^2-24x+144

Problem

x2−24*x+144

Solution

1. Identify the structure of the quadratic expression x2−24*x+144 which follows the form a*x2+b*x+c

2. Recognize that the first term is a perfect square, x2=(x)2 and the last term is a perfect square, 144=12

3. Check if the middle term matches the pattern for a perfect square trinomial, a2−2*a*b+b2=(a−b)2

4. Verify the middle term by calculating 2⋅x⋅12=24*x Since the middle term is −24*x the expression fits the pattern (x−12)2

5. Write the factored form as the square of the binomial.

Final Answer

x2−24*x+144=(x−12)2
