Question

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

Answer 1

Answer:

k =2

Step-by-step explanation:

this answer is done by remainder theorem

Answer 2

Step-by-step explanation:

x-1 = 0

x = 1

g(x) = 1

p(x) = 4x^3 + 3x^2 -5x + k

so, now to find k we will put the value of x as 1 as g(x) = 1

p(1) = 4(1)^3 + 3(1)^2 -5(1) + k

4+3-5+k

2+ k

ATQ:- 0 = 2+k

-2= k
