How To Solve Quadratic Equation In Standard Form?

I don't really understand how to solve them. for example how do you factor a standard form problem?

standard form   f(x) =  a x^2 + b x   + c 

  you can solve it by the Quadratic Formula :

         \(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\)

 

 

or if it is 'easy'   you can solve it by factoring

   example    x^2 + 6x +5 = 0

    factors to    (x+3)(x+2)  = 0       then x = -3 or -2
