Answer:
-5x^2 - 25x + 18
Step-by-step explanation:
-3x ( x + 8 ) + x + 2 ( 9 - x - x^2 ) ( original equation )
-3x^2 - 24x + x + 18 - 2x - 2x^2 ( distribute )
-3x^2 - 2x^2 - 24x + x - 2x + 18 ( order them based on the variables . )
( -3x^2 - 2x^2 ) (- 24x + x - 2x ) ( + 18 ) ( just separated them not a part of solving !! )
-5x^2 - 25x + 18 ( solved , and the answer :) )
Hope its helps !!!

Answer:
It is b.
Step-by-step explanation:
When x is negative x^5 will also be negative.
f(x) = x^5 - 3x^3 + 2x + 4
As x --> -∞ x^5 will be the main factor for f(x) ---> -∞ .
Similarly x^5 will have the greatest influence when x ---> ∞, so f(x) ---> ∞.
