Answer 1

Given question -: find the value of k such that (x-2) is a factor of

$x {3}^{} - 4 {x}^{2} + kx - 4$

Now let's try to solve the question

Given

$x - 2 = 0 \\ x = 2$

Now put the value of x in above equation

${x}^{3} - 4 {x}^{2} + kx - 4 = 0$

${2}^{3} - 4 {}^{2} + kx - 4 = 0$

$8 - 16 + kx - 4 = 0$

$4 - 16 + 2k = 0$

$-12 + 2k = 0$

$2k = 12$

$k = 6$
