$x^2+2x+1-1=3$

Learn how to solve quadratic equations problems step by step online. Solve the quadratic equation x^2+2x=3. Factor the polynomial x^2+2x. Add and subtract \left(\frac{b}{2}\right)^2, replacing b by it's value 2. Now, we can factor x^2+2x+1 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 -1 from both sides of the equation. Canceling terms on both sides.

##  Final answer to the problem

$x=1,\:x=-3$
