plz answer it fast its a request​

Answer 1

Answer:

Step-by-step explanation:

__________

Given -

x-1=>0

x=>1

putting the value of x

p(x)=4x^2-3x+k

p(1)=4(1)^-3(1)+k

0=1+k

k=>-1

Answer 2

Given  :   x -3  is a factor  of  k²x³  - kx²  + 3kx  - k

To find : Value of k

Solution:

x - 3   is a factor of

k²x³  - kx²  + 3kx  - k

=> x = 3  will result in to 0

=> k²3³  - k3²  + 3k(3)  - k = 0

=> 27k² -9k  + 9k  - k = 0

=> 27k²  - k = 0

=> 27k² = k

=> 27k = 1

=> k = 1/27

k = 1/27  if x -3  is a factor  of  k²x³  - kx²  + 3kx  - k
