WebBecause when I you have a quadratic in intercept form (x+a) (x+b) like so, and you factor it (basically meaning multiply it and undo it into slandered form) you get: x^2 + bx + ax + ab. This of course can be combined to: x^2 + (a+b)x + ab. So when you write out a problem like the one he had at. 5:39. x^2 + 15x + 50, 50, which is your "C" term ... WebJan 12, 2024 · How to FOIL.
