Best ResponseYou've already chosen the best response.0then it becomes: \[2x ^{2}+10x ^{2}4x+3x5 \rightarrow \rightarrow 12x ^{2}x5\]

Best ResponseYou've already chosen the best response.0you are basically bunching up all the x^2 terms together, all the x terms together and all the constants together. If you are asked to solve this equation for x, then you can solve it using the formula i gave above for quadratic equations, but if you are not asked to solve for x, don't worry about it just yet.

Best ResponseYou've already chosen the best response.0lol what he's trying to say is, let's expand it and you'll get :\[= 2x^24x5 +10x^2 + 3x\] let's add, and we'll get : \[= 12x^2x5\] done ^_^ , understand it now? :)
