Question

13. P+k is a factor of the polynomial p +kp² -2p +k+4, Find the value
of 'k'.​

Answer 1

Answer:

$p + k = 0 \\ p = - k \\ p + k {p}^{2} - 2p + k + 4 = 0 \\ - k + k \times { - k}^{2} - 2 \times - k +k + 4 = 0 \\ - k - {k}^{3} + 2k + k+ 4 = 0 \\ { - k}^{3} + 2k + 4 = 0 \\ {k}^{3} - 2k - 4 = 0$
