Best ResponseYou've already chosen the best response.0i guess those are the factors you found so saying you got (x+1)(2x+1) but how did you get that?

Best ResponseYou've already chosen the best response.0try multiplying (x+1) and (2x+1) out (x+1)(2x+1) 2x^2+2x+1x+1 2x^2+(2+1)x+1 look at the b term notice in your question that is your b=m+n what happens in our example if you multiply the m and n?
