Answer 2

Answer:

Step-by-step explanation:

Our question is: What is the the formula of the alpha^3 +beta^3

We need to check if there is another way of write the initial formula which is given in the question in another way.

So, lets consider the following formula:

alpha^3 + beta^3 = (alpha + beta) - 3*alpha*beta (alpha + beta)

Another way to write the above equation is the following:

alpha^3 + beta^3 = (alpha + beta)(alpha^2 - alpha*beta+ beta^2)

I hope this helps your studies!!
