Question

expand a3+8b3+c3-6abc​

Answer 1

Answer:

3a+24b+3c-6abc

Step-by-step explanation:

a.3+8b .3+c.3-6abc

Multiply the numbers 8.3=24

=3a+24b+3c-6abc

Answer 2

Step-by-step explanation:a + 2b + c = 0

a + 2b = - c

(a + 2b)³ = (-c)³

a³ + 8b³ + 3(a*2b) (a+2b) = -c³

a³ + 8b³ + 6ab(-c) = -c³

a³ + 8b³ - 6abc = -c³

a³ + 8b³ + c³ = 6abc

Hence proved

An algebraic expression multiplied by itself ( any Number of times) when expressed as a polynomial is called an Expansion.

In fact the term 'expansion' is used for the process of such multiplication.

A corollary is a result or relation that follows from another result or relation that is known.
