Question

the value of k for which x-1 is a factor of 4x square+3x square-4x+k is

Answer 1

Answer:

value of k is -3.

Step-by-step explanation:

Let P(x)=4x² + 3x² - 4x + k

Given, (x−1) is a factor of P(x)

Given, (x−1) is a factor of P(x)x−1=0

Given, (x−1) is a factor of P(x)x−1=0x=1∴ p(1)=4×(1)² + 3(1)² - 4(1) + k = 0

4 + 3 - 4 + k = 0

k+3=0

k+3=0k=−3

k+3=0k=−3Hence, the value of k is −3.

hope this answer helps you.....take care!!
