I got:
by multiplying each factor....
x^4 - 2x^3 - 2x^2 + 2x^3 - 4x^2 - 4x + 3x^3 - 6x - 6
then combining like terms....
answer is:
x^6 - 3x^2 - 10x - 6
(4x)(-3x^8)(-7x^3)
4 (-3)(-7) = 84
x(-x^8)(-x^3) = x^(1 + 8 + 3) = x^12
Answer: 84x^12
chris started with 27 ( where the dot is at X=0)
Connie started at 9 ( because it doesn't have a letter with it)
The answer is A..Need an explanation?
