Best ResponseYou've already chosen the best response.0So for example 3w^2 + 12w + 9 = 3(w^2 + 4w +3) = 3(w^2 + w + 3w + 3) < how did they get this part?

Best ResponseYou've already chosen the best response.1Looks like they just separated 4w into w + 3w ?

Best ResponseYou've already chosen the best response.1But if you are asking why they chose to do it that way, it is because this particular arrangement allows you to factor w^2 + w + 3w + w into w(w + 1) + 3(w + 1) = (w + 1)(w + 3). Alternatively you could have looked at w^2 + 4w + 3 and ask what two numbers multiply to 3 and add to 4? 1 and 3 Thus w^2 + 4w + 3 = (w + 1)(w + 3)

Best ResponseYou've already chosen the best response.1I meant to say: w^2 + w + 3w + "3" into w(w + 1) + 3(w + 1)
