Question

the value of k, if (x - 1) is a factor of 4x³ + 3x² - 4x + k, is​

Answer 1

Answer:

$put \: x = 1 \\ \\ 4 + 3 - 4 + k = 0 \\ \\ k = - 3$

Answer 2

Answer:

since x-1 is a factor therefore x=1

then 4x1x1x1+3x1x1-4x1+k=0

        4+3-4+k=0

        (4 and -4 gets cancelled)

        3+k=0

          k=-3
