Re: HSC 2013 3U Marathon Thread Prove by mathematical induction that if p is a positive integer then (1+p)^n -1 is divisible by p for all values of n > or equal to 1. Hence deduce that 12^n - 4^n -3^n +1 is divisible by 6 for all positive integers n> or equal to 1.

sub x = b and x=-b into the polynomial to obtain 2 equations. 16b^4 -32b^3 +16b^2 +kb -5 = 0 16b^4 +32b^3 +16b^2 -kb -5 = 0 You can then add these 2 equations and find b. (b = +-1/2) Once you find b, sub it back into the polynomial to find k. Btw, is this a troung student since this question...
