plz guys answer it fast and correctly. ​

Answer 1

Step-by-step explanation:

Hey mate , here is your answer .

METHOD 1

PROOF :-

X^3 + Y ^3

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

= (x+y) [ x^2 + y^2 + 2xy - 3xy ]. {using ( a + b )^2 = a^2 + b^2 + 2ab }

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

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

Hence , proved

Method 2

Proof : (a+b) • (a2-ab+b2) =

a3-a2b+ab2+ba2-b2a+b3 =

a3+(a2b-ba2)+(ab2-b2a)+b3=

a3+0+0+b3=

a3+b3

Please mark it as brainliest and follow me .♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
