Polynomial Question (1 Viewer)

[FromDeeEast]

I've spent about 20 minutes today pondering how i would approach this question and i havent came a conclusion yet, so i would appreciate any help i can get

the question is from arnold and arnold (aka camb) : Exercise 4.2 Q8

the question has alot of super script etc so since most people have either book would any 1 be able to help? if no 1 wants to write it up can you just gimme a hint

 

[ianc]

it would be a lot better if you wrote up the question......

when doing an indice, surround it with the tags [noparse]^indice[/noparse]

eg for x², type [noparse]x²[/noparse]


Even if people have the cambridge textbook, it is easier to read it off the screen rather than having to look it up in a book


other than that, im more than happy to help you

Show that the polynomial P₁(z) = b_nzⁿ + b_{n - 1}z^{n- 1} + ... + b₀ and P₂ = c_n + c_nzⁿ + c_{n -1} z^{n - 1} + .... + c₀ are equal for more then n values of z, then b_n = c_n, b_n-1 = c_n-1, ..... , b₀ = c₀

thats should be it
