Simplify the following polynomial and write the answer in standard form.
(-2x^2 +5x² - 4x+8) - (-2x^2 + 2x - 3)
A. 5x^2 - 6x +11
B. –2x+5+5x^2
C. 4x^3 + 5x^2 - 6x - 11
D. 5x^2 - 6x – 11+4x^3

Your answer would is A. Thats the standard form

A:5x^2 - 6x +11

you wrote it wrong on so i did the work based off the picture you attached.

attached picture work:
(-2x^3+5x^2-4x+8)-(-2x^3+2x-3)
distribute the negative to the second equation and flip the signs inside the parentheses.
(-2x^3+5x^2-4x+8)+(2x^2-2x+3)
cancel out the -2x^3 and the 2x^3
(5x^2-4x+8)+(-2x+3)
add both together
5x^2-6x+11

your answer is A. 5x^2 -6x +11

You would plot 83 on the 83 line and you would plot -113 on the -113 line.

Hope this ; )
