Show that one and only one out of n,n+2,n+4 is divisible by 3, where n is any positive integer.

By Euclid division lemma:

Let â€˜aâ€™ be any positive integer such that a = 3q +r, where 0 â‰¤ r < 6 and q is not equal to zero

Thus a= 3q, a= 3...

Sir, Can you please solve the following:-

If the polynomial X^{4}- 6X^{3}+16X^{2}-25X+10 is divided by another polynomial X^{2}-2X+k, the reminder is X+a . Find k and a

Answer.

Given that the remainder is (x + a)

â‡’ (4k â€“ 25 + 16 â€“ 2k)x + [10 â€“ k(8 â€“ k) ] = x + a

â‡’ (2k â€“ 9)x + [10 â€“ 8k + k^{<...}

Given that the remainder is (x + a)

â‡’ (4k â€“ 25 + 16 â€“ 2k)x + [10 â€“ k(8 â€“ k) ] = x + a

â‡’ (2k â€“ 9)x + [10 â€“ 8k + k
