$21\left(x^2+\frac{4}{7}x-\frac{10}{21}\right)=0$
Learn how to solve quadratic equations problems step by step online. Solve the quadratic equation 21x^2+12x+-10=0. 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{4}{7}x+\frac{4}{49}. Divide both sides of the equation by 21.
