Find the solutions to the following equation x^2 - 5*x + 6 = 0

There are several ways one can go about answering this question, one of which is to 'complete the square' by trial and error. A different, potentially easier method is to substitute the coefficients into the the Quadratic formula. Answer: x^2 - 5x + 6 = (x-2)(x-3) = 0, therefore either (x-2) or (x-3) must equal zero. x - 2 = 0 , x - 3 = 0, x = +2, x = +3
