Best ResponseYou've already chosen the best response.0I know how to set it up to solve it, and if it were a regular equation without variables like "7(3x+10)" I know I would have to distribute the 7 but when I set up my problem I'm not sure how I would distribute, or what the first step would be. @BIue

Best ResponseYou've already chosen the best response.0So if I set it up it would look like (3x^2x+2)(5x^21). If I distribute like regular I would get 15x^43x^25x^3+x+10x^22. Then I would simplify, correct? @BIue

Best ResponseYou've already chosen the best response.0Then after I simplify that, I got 15x^45x^3+7x^2+x2. Would that be my final answer? @BIue

Best ResponseYou've already chosen the best response.1what you are setting up would be correct to find f* g but this question is different .

Best ResponseYou've already chosen the best response.1after you set it up you will use the distributive property, like in your example, to simplify
