Show that (a - b)+(b-c)+(c -a)3 = 3 (a - b) (b -c) (c-a)

nikdorinn [45]

Answer:

I think that it should be

${(a - b)}^{3} + {(b - c)}^{3} + {(c - a)}^{3} = 3(a - b)(b - c)(c - a)$

Step-by-step explanation:

Here,

we take , a - b = A,b-c = B , c - a= C

A+B+C = 0

we know that,

${a}^{3} + {b}^{3} + {c}^{3} - 3abc = (a + b + c)( {a}^{2} + {b}^{2} + {c}^{2} - ab - bc - ca)$

Here , A+B+C = 0

so,

A^3 +B^3 + C^3 = 3 ABC

now we put the values

${(a - b)}^{3} + {(b - c)}^{3} + {(c - a)}^{3} = 3(a - b)(b - c)(c - a)$

I am done .
