Answer 1

Answer:

x= 3

put the value of x

k square (3)cube - k(3) square+ 3k(3) - k = 0

27ksquare - 9k + 9k - k= 0

27k square - k = 0

27k square= k

1/27 = k square/ k

1/27 = k

hence, value of k is 1/27.......

Answer 2

Answer:

$x = 3. \\ {k}^{2} {x}^{3} - k {x}^{2} + 3kx - k \\ {k}^{2}( {3}^{3} ) - k {3}^{2} + 3k \times 3 - k \\ 27 {k}^{2} - 9k + 3k - k \\ 27 {k}^{2} - 6k - k \\ 27 {k}^{2} - 7k.$
