Question

(x+y)(x2-xy+y)
plz answer my question ​

Answer 1

Answer:

x^3 + y^3

Step-by-step explanation:

This is quite straight forward, it is an identity.

The identity says--->

x^3 + y^3 = (x+y)(x^2-xy+y^2)

So that is the answer.

If you want to verify it, open the brackets on RHS and you will get the same answer as of LHS.

HOPE IT HELPS !

PLEASE MARK AS BRAINLIEST :)

Answer 2

Answer:

x³ + y² - xy² + xy

Step-by-step explanation:

( x + y ) ( x² - xy + y )

= x ( x² - xy + y ) + y ( x² - xy + y )

= x³ - x²y + xy + x²y - xy² + y²

= x³ + y² - xy² + x²y - x²y + xy

= x³ + y² - xy² + xy
