Question

When ( x3 + 3x2 – kx + 4) is divided by (x-2), the remainder is k, Find the value
of k.

Answer 1

Answer:

Value of k = 8

Step-by-step explanation:

Let p(x)= x³+3x²-kx+4,

If p(x) divided by (x-2) then the remainder is p(2)

p(2) = k (given)

=>2³+3(2²)-k×2+4 = k

=> 8+12-2k+4 = k

=> 24-2k-k = 0

=> -3k = -24

=> k = (-24)/(-3)

=> k = 8

Therefore,

Value of k = 8
