The value of k for which x-1 is a factor of 4x3+3x2-4x+k, is

Since, x-1 is a factor of f (x)Therefore,f (1) = 04 (1)3 + 3 (1)2 - 4 (1) + k = 04 + 3 - 4 + k = 0k = - 3

The value of k for which x-1 is a factor of 4x³+3x²-4x+k, is

Since, x-1 is a factor of f (x)

Therefore,

f (1) = 0

4 (1)³ + 3 (1)² - 4 (1) + k = 0

4 + 3 - 4 + k = 0

k = - 3

If x+1 is a factor if the polynomial 2x²+kx, then k =

If x + a is a factor of x⁴-a²x²+3x-6a, then a =

If both x-2 and x are factors of px²+5x+r, then

If x²-1 is a factor of ax⁴+bx³+cx²+dx+e, then
