Answer 2

To simplify the expression, we need to multiply the two factors together:

Expression: (х + 1) * (х^2 - 3х - 4)

To do this, we use the distributive property, which states that (a + b) * c = a * c + b * c. Applying this to the given expression:

(х + 1) * (х^2 - 3х - 4) = х * (х^2 - 3х - 4) + 1 * (х^2 - 3х - 4)

Now, we'll perform the multiplications:

1. х * (х^2 - 3х - 4) = х^3 - 3х^2 - 4х
2. 1 * (х^2 - 3х - 4) = х^2 - 3х - 4

Putting it all together:

(х + 1) * (х^2 - 3х - 4) = х^3 - 3х^2 - 4х + х^2 - 3х - 4

Next, let's combine like terms:

Grouping the terms with the same power of x:

(х^3 + х^2) + (-3х^2 - 3х) + (-4х - 4)

Now, combine the terms within each group:

х^3 + (х^2 - 3х^2) + (-3х - 4х) - 4

Simplifying further:

х^3 - 2х^2 - 7х - 4

So, the simplified expression is: х^3 - 2х^2 - 7х - 4.
