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
