Answer 2

Answer:

hey mate

Step-by-step explanation:

here is your answer

(a + b + c)³ = a³ + b³ + c³ + 3(a + b) (b + c ) (c + a )

solution

= [(a+b) + c]³

= (a + b)³ + c³ + 3 (a+b) c [(a + b) + c]

= a³+ b³ + c³ + 3ab (a + b) c [a + b + c ]

= a³ + b³ + c³ + 3ab (a+b) + 3ca (a + b) + 3bc (a + b) + 3c² (a + b)

= a³ + b³ + c³ + 3 (a + b) [ab + bc + ca + c²]

= a³ + b³ + c³ + 3 (a +b) [ b(a + c) + c (a + c)]

= a³ + b³ + c³ + 3 (a +b) (c + a ) ( b + c)

arranging

= a³ + b³ + c³ + 3 (a + b ) (b + c ) (c + a)
