Nice explanation. A short cut if u will ... Once you know the first binomial by inspection you can find the 2nd... In your 2nd example 20x^2 - 47x + 24, once you know ( 4x - 3 ) the only other way to get 20x^2 and +24 are multiplication of first term by 5x and 2nd term by -8 hence ( 5x - 8 ) ... a quick FOIL check proves your answer
