Question

what is the algebraic identiy x cube+ y cube?

Answer 1

Answer:

Step-by-step explanation:

Factorization of x3 + y3

                 It can be seen in most book that x3 + y3 can be factorized by dividing the expression by  (x + y).  After division we get a quotient of  (x2 - xy + y2) with no remainder.  Therefore                          

However, this method involves knowing the factor (x + y) beforehand (and the understanding of Factor Theorem). This article deals with different methods of handling this factorization.

 

 

(Method 1) (Binomial theorem)

 

                 =

Move the last two terms to the other side, we get:

 

                 =  

                 

Answer 2

x cube + y cube
