Question

Evaluate (x+2) (x square - 2xy+4y square) by using identiy

Answer 1

Answer:

Ur ans is x³ + 8y³ + 6xy ( x + y )

Step-by-step explanation:

I think in the question it's not ( x + 2) but instead ( x + 2y )

( x + 2y ) ( x² - 2xy + 4y² ) this is the question

=> ( x + 2y ) [ x² - 2xy + ( 2y )² ]

As we can see the equation [ x² - 2xy + ( 2y )² ] is in the form of ( a + b )² = ( a² + b² + 2ab )

=> ( x + 2y ) ( x + 2y )²

=> ( x + 2y )³

As we know that ( a + b )³ = a³ + b³ + 3ab( a + b)

=> x³ + 8y³ + 6xy ( x + y )

Hope this helps uh....!!!!!!!
