Best ResponseYou've already chosen the best response.0well, this is the easiest of all Maths @Takirap2000. aLL YOU NEED TO DO IS TO SUBTRACT TERMS WITH THE SAME POWERS. For example, 3x^2 4x^2 gave you x^2, I think you can do the rest. But if D is your answer, I am soo sure that you wanted to write 5x in your second equation. Check it.

Best ResponseYou've already chosen the best response.0yes, I am saying subtract terms that have the same powers, 3x^2  4x^2 because their power is 2, and 2x5x because their power is 1 or x is to the power 1, and then the constants 5 (1)
