Given : x -2 is a factor of x³ - 6x² + 11x + k
To find : Value of k
Solution:
x -2 is a factor of x³ - 6x² + 11x + k
putting x= 2 will result into 0
=> 2³ - 6(2)² + 11(2) + k = 0
=> 8 - 24 + 22 + k = 0
=> k = - 6
x + 1 divided 5x³ + 11x² + 4x - p
=> x = -1 will result into 0
=> 5(-1)³ + 11(-1)² + 4(-1) - p = 0
=> -5 + 11 - 4 - p = 0
=> p = 2
4x - 1 Divides 4x³ - 5x² - kx + 3
=> x = 1/4 will result into 0
=> 4(1/4)³ -5(1/4)² -k/4 + 3 = 0
=> 1/16 - 5/16 -k/4 + 3 =0
=> -1/4 - k/4 + 3 = 0
=> -1 - k + 12 = 0
=> k = 11
Similarly others can be done
