$10\left(x^2+\frac{9}{10}x+\frac{6}{5}\right)=0$
Learn how to solve quadratic equations problems step by step online. Solve the quadratic equation 10x^2+9x+12=0. Use the complete the square method to factor the trinomial of the form ax^2+bx+c. Take common factor a (10) to all terms. Add and subtract \displaystyle\left(\frac{b}{2a}\right)^2. Factor the perfect square trinomial x^2+\frac{9}{10}xx+\frac{81}{400}. Subtract the values \frac{6}{5} and -\frac{81}{400}.
