Best ResponseYou've already chosen the best response.0Ax^2 +Bx +C is not a formula. If you are asking, when should I use the quadratic formula to find the roots of Ax^2 +Bx +C = 0 I would say, any time you can not easily factor the quadratic. for example x^2 + 2x +1 can be factored into (x+1)(x+1), so its roots are 1 (repeated) you could also do x =(1/2)*(2 ± sqrt(44)) = 1 (twice)
