$8\left(x^2+\frac{15}{8}x+\frac{15}{8}\right)=0$
Learn how to solve problems step by step online. Solve the quadratic equation 8x^2+15x+15=0. Use the complete the square method to factor the trinomial of the form ax^2+bx+c. Take common factor a (8) to all terms. Add and subtract \displaystyle\left(\frac{b}{2a}\right)^2. Factor the perfect square trinomial x^2+\frac{15}{8}xx+0.878906. Subtract the values \frac{15}{8} and -0.878906.
