$81\left(x^2-\frac{4}{9}x+\frac{4}{81}\right)$
Learn how to solve polynomial factorization problems step by step online. Factor by completing the square 81x^2-36x+4. Use the complete the square method to factor the trinomial of the form ax^2+bx+c. Take common factor a (81) to all terms. Add and subtract \displaystyle\left(\frac{b}{2a}\right)^2. Factor the perfect square trinomial x^2+-\frac{4}{9}xx+\frac{4}{81}. Subtract the values \frac{4}{81} and -\frac{4}{81}.
