Question

Find the value of k if x-1 is a factor of p(x)=4x degrees 3+3x degrees 2-4x+k

Answer 1

Answer:

- 3

Step-by-step explanation:

If x - 1 is factor of this polynomial, numeric value of that polynomial must be 0, for x = 1.

= > 4(1)³ + 3(1)² - 4(1) + k = 0

= > 4(1) + 3(1) - 4(1) + k = 0

= > 4 + 3 - 4 + k = 0

= > 3 + k = 0

= > k = - 3

Answer 2

SOLUTION:-

➡ If X - 1 is factor of this polynomial, numeric value of that polynomial must be 0, for

x = 1

=> 4(1)³+3(1)²-4(1)+k = 0

=> 4(1)+3(1)-4(1)+k = 0

=> 4+3-4+k = 0

=> 3+k = 0

=> k = -3✔
