    its easy assume the quadratic equation to be y=ax^2 + bx + c now put the values of the co-ordinates in the place of x and y there are three co-ordinates so, you'll get three equations you have three variables, a, b and c solve the three equations for three variables and voila! you get the quadratic equation
