k = 7/5

step-by-step explanation:

4${x}^{3}$ + 3${x}^{2}$ = 4k + k

Now,

(x - 1) is a factor if the given expression,

therefore,

x - 1 = 0

=> x = 1

satifies the given expression,

therefore,

putting the value of x = 1,

we get,

=> 4 × ${1}^{3}$+ 3 × ${1}^{2}$ = k(4+1)

=> 4 + 3 = k(4+1)

=> k = 7/(4+1)

=> k = 7/5

Hence,

the value of k = 7/5
