can anyone help me simplify the expression x^2 + 4x - 21/6x^2 + 19x + 3 * 36x^2 - 1/6x^2 + 41x -7? I think the answer is 3-x/3 + x but I am not sure?

x^2 + 4x - 21/6x^2 + 19x + 3 * 36x^2 - 1/6x^2 + 41x -7 This is set up like fraction and the first oneis x^2 + 4x - 21 over 6x^2 + 19x 3 then the mutipilication sign is in between these problem mutipling it 36^2 - 1 over 6x^2 +41x - 7. I hope this is better, I wish we could drawn the lines in between the fractions.lol

((x^2 + 4x - 21)/(6x^2 + 19x + 3) * (36x^2 - 1)/(6x^2 + 41x -7) =
((x + 7)(x - 3)/((6x + 1)(x + 3))) * (6x + 1)(6x - 1)/((6x - 1)(x + 7)) =
((x + 7/(x + 7))((x - 3)/(x + 3))((6x + 1)/(6x + 1))((6x - 1)/(6x - 1)) =
(x - 3)/(x + 3)
which is the negative of your answer.

I don't understand the expression. Could you add some parentheses so that it is more easily understood when written on one line?
