What is the positive solution to the equation 0 equals negative x squared plus 2 x plus 1

The solution is x=1. This video can give you a better explanation of quadratics than I can. If you look up solving quadratics on youtube, it could probably give you a better explanation than I can. Anyways, I worked out the problem using the x method to find its factors, which turned out to be - 1. In factored form, the equation is (x-1) (x-1) = 0. When x=1, the equation will equal 0.
