Question

If (x-1) is a factor of P(x)=〖4x〗^3+〖3x〗^2-4x +K , then find the value of K.​

Answer 1

Answer:

k=-3

Step-by-step explanation:

4x^3+3x^2-4x+k=0 , x-1 is the factor of the given polynomial

therefore , x=1

4(1)^3+3(1)^2-4(1)+k=0

4+3-4+k=0

7-4+k=0

3+k=0

therefore,k=-3

hence found the value
