Hey there !

Solution:

Given that, ( x - a ) is a factor of x³ - a²x + x + 2

=> p ( x ) = a

Substituting the value of x as 'a' we get,

=> a³ - a² ( a ) + a + 2 = 0

=> a³ - a³ + a + 2 = 0

=> a + 2 = 0

=> a = -2

Hence the value of a is -2.

Second Question,

Given that ( x - 3 ) is a factor of k²x³ - kx² + 3kx - k

=> p ( x ) = 3

Substituting x as 3 in the equation we get,

=> k² ( 3³ ) - k ( 3² ) + 3k ( 3 ) - k = 0

=> 27k² -9k +9k - k = 0

=> 27k² - k = 0

=> k ( 27k - 1 ) = 0

=> k = 0 or k = ( 1 / 27 )

Hope my answer helped !
