Correct Question

Find k if x-2 is a factor of 7x^3-3x^2+5x+4k

Given

  • A cubic Polynomial

  • 7x^3-3x^2+5x+4k
  • x-2 is a factor

To find

  • Value of k

Solution

Here if we put the value of factor in Polynomial than Equation become zero

  • X-2 = 0
  • X = 2

putting value in the Polynomial

=>7x^3-3x^2+5x+4k

=>7×(2)³-3(2)²+10+4K=0

=>56-12+10+4K=0

=>4K=-54

=>K= -27/2

Hence the value of k is -27/2
