Best ResponseYou've already chosen the best response.0you multiply the 1st and the last number, 10 * 15 = 150

Best ResponseYou've already chosen the best response.0now you will find the factors of 150 such as 1&150 2&75 3&50 ...

Best ResponseYou've already chosen the best response.0while you are doing that, you will check if there is any way that you can combine those factors to get the middle coefficient, in our case 19 you will see that 6 and 25 (factors of 150) can be combined as 625 = 19

Best ResponseYou've already chosen the best response.0so once you find that out, you car write 10w^2 19 w 15 as 10w^2  25w + 6w 15, so if you do factoring by grouping, 5w(w5) + 3(w5) and finally (5w+3)(w5)
