$\frac{x^2-16}{x^2-6x+18+9-9}$
Learn how to solve polynomial factorization problems step by step online. Factor by completing the square (x^2-16)/(x^2-6x+18). Add and subtract \displaystyle\left(\frac{b}{2a}\right)^2. Factor the perfect square trinomial x^2+-6x+9. Subtract the values 18 and -9. Simplify \sqrt{x^2} using the power of a power property: \left(a^m\right)^n=a^{m\cdot n}. In the expression, m equals 2 and n equals \frac{1}{2}.
