The variables A, B, and C represent polynomials where A = x2, B = 3x + 2, and C = x – 3. What is AB – C2 in simplest form? 3x3 + 2x2 – x + 3 3x3 + 2x2 – x – 3 3x3 + x2 – 6x + 9 3x3 + x2 + 6x – 9

A=2x
B=3x+2
C=x-3
AB=2x (3x-2)=6x^2-4x
2C=2 (x-3)=2x-6
AB-2C=6x^2-4x-2x+4
=6x^2-6x+4
B=3x+2
C=x-3
AB=2x (3x-2)=6x^2-4x
2C=2 (x-3)=2x-6
AB-2C=6x^2-4x-2x+4
=6x^2-6x+4

is it right? ??
no its not on the answer choices
okk
then write ur answers choices in right way
2x3 − x2 + 16x + 3
2x3 − 11x2 + 16x + 3
2x3 − 11x2 + 16x − 3
2x3 − x2 + 16x − 3
2x3 − 11x2 + 16x + 3
2x3 − 11x2 + 16x − 3
2x3 − x2 + 16x − 3
waait wrong one
3x3 + 2x2 – x + 3
3x3 + 2x2 – x – 3
3x3 + x2 – 6x + 9
3x3 + x2 + 6x – 9
3x3 + 2x2 – x – 3
3x3 + x2 – 6x + 9
3x3 + x2 + 6x – 9
those are the right ones above
sorry I can't do this
because did not got it
