Hi,         
As to 'solving' Quadratic Equations of the form y = ax^2 + bx + c
Finding x such that y = 0 can be done either by:
1)factoring (showing using quadratic formula naturally has the same results)
 ex: x^2 -2x - 3 = 0 factors to (x-3)(x+1)=0 with x = 3 or x = -1
{{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}} {{{x = (2 +- 4)/(2)}}} x-= -1 or x = 3
2) When factoring does not seem to work for us, the Quadratic formula always will
