I am trying to understand what the purpose/application of factoring as in quadratics is.
There are several reasons why you would factor an quadratic equation, however, the first that comes to my mind is solving for roots or for the x-value(s). Ex) x^2-2x=-1 x^2-2x+1=0 If we factor: (x-1)(x-1)=0 From this we can see that x=1, so that's our x-value for this equation. You can double check that by plugging back in: 1-2+1=0 ... Check
