Show all work. Thanks in advanced.

Answer 1

showing my work is a little hard but I can try, but the answer is -2x^2+15x+25 with a remainder of -87/(x-3). First I take -2x^3 and I find out what I need to multiply x-3 to get -2x^3 and that is -2x^2, now you can see where I got that term from. Next I multiply x-3 by -2x^2 and I get -2x^3 +6x^2, and I subtract that from -2x^3+21x^2 and that leaves me with 15x^2, I repeated the steps I just showed you for x^2 and x, and you can see with 15x^2 I need to multiply (x-3) by 15x as I have in the answer. Hope this helped, cheers.
