Answer 1

Answer:

I don't understand what your saying

Answer 2

The value of k is -4.

Step-by-step explanation:

The expression is:

$x-3x+4x+k$

The expression is divisible by (x - 2), i.e. (x - 2) is a factor of thee expression.

Then x = 2 is going to satisfy the expression.

Substitute x = 2 in the expression and solve for k as follows:

$x-3x+4x+k=0$

              $2x+k=0$

                      $k=-2x\\k=-2\times 2\\k=-4$

Thus, the value of k is -4.
