Question

Verify : (I) x³ + y³ = (x+y)(x² - xy + y²)

Answer 1

HELLO!!!!
__________________________________
➡️x3+y3 = (x+y)(x^2-xy+y^2)
--------------------
R.H.S
(x+y)(x^2-xy+y2)
=>x3-x^2y+xy^2+x^2y-y^2x+y3
NOW after cancelling we get :
=> x3+y3
-------------------
L.H.S
=> x3+y3
L.H.S. = R.H.S
Hence VERIFIED✔✔

Answer 2

hello, here is your answer by Sujeet,

From R.H.S

(x+y)(x²-xy+y²)

x(x²-xy+y²) +y(x²-xy+y²)
x³-x²y+xy²+x²y-xy²+y³

Cancelling -x²y+x²y and. xy²-xy²

then,
we get
x³+y²




that's all.....:) :)
