$x^2+10x+25-25=49$

Learn how to solve quadratic equations problems step by step online. Solve the quadratic equation x^2+10x=49. Factor the polynomial x^2+10x. Add and subtract \left(\frac{b}{2}\right)^2, replacing b by it's value 10. Now, we can factor x^2+10x+25 as a squared binomial of the form \left(x+\frac{b}{2}\right)^2. We need to isolate the dependent variable x, we can do that by simultaneously subtracting -25 from both sides of the equation. Canceling terms on both sides.

 Final answer to the problem

$x=-5+\sqrt{74},\:x=-5-\sqrt{74}$
