Best ResponseYou've already chosen the best response.1\[\huge\rm\color{blue}{ }\color{ReD}{x}^2+2\color{ReD}{x}\]this is the function replace x with 3 \[\huge\rm \color{blue}{}(\color{ReD}{3})^2+2(\color{ReD}{3})\] \[\huge\rm \color{blue}{}(\color{ReD}{9})6\] (3)^2 =9 but i'm saying blue sign would stay there
