Prove a3+b3=(ab)(a2+b2+ab) by activity - Brainly.in​

Answer 1

Step-by-step explanation:

To prove that: - = (a - b)( + + ab).

Solution:

R.H.S. = (a - b)( + + ab)

= a( + + ab) - b( + + ab)

= + a + b - b - - b

= + (a - a) + (b - b) -

= + 0 + 0 -

= -

= L.H.S., proved

∴ - = (a - b)( + + ab), proved.

Thus, - = (a - b)( + + ab), proved.
