Best ResponseYou've already chosen the best response.0for the second half of the question you need to distribute the negative sign. so it becomes: (7x^2+2x+3) so the full equation now is (5x^2+2x5)(7x^2+2x3) Then you subtract life terms. So it is: 5x^2(7x^2)=2x^2 then: 2x+2x=4x then: 5(3)=2 so it would come out to: 2x^2+4x2

Best ResponseYou've already chosen the best response.0BUT you only distribute the negative sign when its a subtraction problem, not addition. and yes. the answer at the bottom is the full answer.

Best ResponseYou've already chosen the best response.0yesss. i did the equation horizontally, but it might be easier to do it vertically. look at the problem like this\[5x^2+2x5\over7x^22x3\] think of the line in the middle as the line that tells you to subtract. since all the like terms are lined up it makes it easier.
