Answer:
-x^4 - 2x^3 +2x + 5
Step-by-step explanation:
(x + 3) – [(x + 2) (xᶺ3 – 1)]
(x + 3) - [(x^4 - x + 2x^3 - 2)]
(x + 3) - (x^4 - x + 2x^3 - 2)
-x^4 - 2x^3 +2x + 5
Answer:
[tex] -x ^ 4 - 2x ^ 3 + 2 x + 5 [/tex]
Step-by-step explanation:
We are given the following expression and we are to simplify it:
[tex](x + 3) - [(x + 2) (x^3-1)][/tex]
We will start by removing the parenthesis:
[tex]x+3-\left(x+2\right)\left(x^3-1\right)[/tex]
Now expanding the terms [tex]-\left(x+2\right)\left(x^3-1\right)[/tex] to get:
[tex] x + 3 - x ^ 4 + x - 2 x ^ 3 + 2 [/tex]
Simplifying it further to get:
[tex] -x ^ 4 - 2x ^ 3 + 2 x + 5 [/tex]
