hey pls expln this....if f(x) = ${({rm{1 + x + }}{{rm{x}}^2} + {x^3} + .......{x^{2012}})^2} - {x^{2012}}$
g(x) = ${rm{1 + x + }}{{rm{x}}^2} + {x^3} + .......{x^{2011}}$
Then what is the remainder when f(x) is divided by g(x
A sum of rs 3000 is distributed amongst A, B, and C. A gets 2/3 of what B and C got together and c gets 1/3 of what A and B got together, C's share is?
