$x^2+6x=5-8$
Learn how to solve quadratic equations problems step by step online. Solve the quadratic equation x^2+6x+8=5. Group the terms of the equation by moving the terms that have the variable x to the left side, and those that do not have it to the right side. Subtract the values 5 and -8. Factor the polynomial x^2+6x. Add and subtract \left(\frac{b}{2}\right)^2, replacing b by it's value 6. Now, we can factor x^2+6x+9 as a squared binomial of the form \left(x+\frac{b}{2}\right)^2.
