Math Problem Statement

A^3-1

Solution

The expression A31A^3 - 1 can be factored using the difference of cubes formula. The formula for the difference of cubes is:

x3y3=(xy)(x2+xy+y2)x^3 - y^3 = (x - y)(x^2 + xy + y^2)

In your case, A31A^3 - 1 can be written as:

A313A^3 - 1^3

Using the difference of cubes formula:

A31=(A1)(A2+A1+12)A^3 - 1 = (A - 1)(A^2 + A \cdot 1 + 1^2)

Simplifying further:

A31=(A1)(A2+A+1)A^3 - 1 = (A - 1)(A^2 + A + 1)

So, the factored form of A31A^3 - 1 is:

(A1)(A2+A+1)(A - 1)(A^2 + A + 1)
