Question

Find the value of k , if ( x-1 ) is a factor of 4x3 + 3x2+5x +k

Answer 1

Given,

(x - 1) is a factor of a polynomial

p(x) = 4x³ + 3x² + 5x + k

find the value of “ k ” .

Solution :

if x - 1 is a factor.

x - 1 = 0

x = 1

on substituting the value,

$4( {1)}^{3} + 3 {(1)}^{2} + 5(1) + k = 0$

$4 + 3 + 5 + k = 0$

$k = - 12$

FINAL ANSWER :

Value of k is -12 .

Answer 2

Answer:

value of k is = -12
