ax^2 + bx + c = 0
(ax + (ac/b-c)) (x + (b-c)/a) = 0
if wrong, sorry

You'll typically use it when solving a quadratic equation - when factoring isn't obvious.
When the equation is a polynomial whose highest order (power) is 2. Eg. y= x2 + 2x + 10. Then you can use quadratic formula to solve if factoring is not possible.
When solving a quadratic equation by factoring, we set each factor equal to zero because of the Zero Product Property. This property states that if the product of two factors is zero, then at least one of the factors must be zero. By setting each factor to zero, we can find the specific values of the variable that satisfy the equation, leading to the solutions of the quadratic equation.
