WebStep-by-step solution. 1. Find the coefficients. 2. Find two numbers which product equals to and sum equals to. Because the product of coefficient and coefficient equals a positive number both factors need to be either positive or negative. From the list of factors, find a pair which sum equals to the coefficient.
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 ...
