$21\left(x^2+\frac{11}{21}x-\frac{2}{21}\right)$
Learn how to solve polynomial factorization problems step by step online. Factor by completing the square 21x^2+11x+-2. Use the complete the square method to factor the trinomial of the form ax^2+bx+c. Take common factor a (21) to all terms. Add and subtract \displaystyle\left(\frac{b}{2a}\right)^2. Factor the perfect square trinomial x^2+\frac{11}{21}xx+\frac{19}{277}. Subtract the values -\frac{2}{21} and -\frac{19}{277}.
