Answer:
x^3 - 1
Step-by-step explanation:
(x^2 + x + 1) (x - 1)
Here we have to use the distributive property.
(x^2 + x + 1)x -1(x^2 + x + 1)
Now distribute x and -1 inside the parenthesis, we get
x^3 + x^2 + x -x^2 - x - 1
Now we have to simplify the like terms.
x^3 + x^2 -x^2 + x - x -1 [x^2 - x^2 =0; x -x = 0]
= x^3 - 1
The answer is x^3 - 1
Thank you.
Answer:

Step-by-step explanation:
75÷5-[(9-7)×3]×2
do innermost inclusion symbols first, which would be 9-7
75÷5-[2×3]×2
