Expand $(x+1)(x^{2}+1)(x-1)$. What is the sum of the coefficients of the resulting expression?

0

Step-by-step explanation:

Hello, please consider the following.

For any a and b real numbers we can write.

We apply this formula two times here, as below.

We have the coefficient of 1 for and the constant term is -1, so the sum of the coefficients is 0.

Thank you.

the answer is true.

step-by-step explanation:

4

step-by-step explanation:

6 (donuts) divided by 3 is 2.

so 2/3 means 2 times 2, which is 4/6.
