1.	(a2-b2)3+(b2-c2)3+(c2-a2)3(a-b)3 + (b-c)3 + (c-a)3=(a) 3(a + b) ( b+ c) (c + a)(b) 3(a − b) (b − c) (c − a)(c) (a − b) (b − c) (c − a)(d) none of these
Answer» $\frac{(a^{2} - b^{2})^{3} + (b^{2} - c^{2})^{3} + (c^{2} - a^{2})^{3}}{(a - b)^{3} + (b - c)^{3} + (c - a)^{3}} =$ (a) 3(a + b) ( b+ c) (c + a) (b) 3(a − b) (b − c) (c − a) (c) (a − b) (b − c) (c − a) (d) none of these
