Question

Find the value of “k”, if x – 1 is a factor of 2x^3 + 5 x ^2 - 3x + 2k​

Answer 1

Answer:

answer for the given problem is given

Answer 2

Answer:

k = -2

Step-by-step explanation:

Since x-1 is a factor , therefore, x=1 is the zero of the p{x}

Now,

2(1)^3 + 5(1)^2 - 3(1) + 2k = 0

2(1) + 5(1) - 3(1) + 2k = 0

2 + 5 - 3 + 2k = 0

7 - 3 + 2k = 0

4 + 2k = 0

2k = - 4

Therefore , k = -4/2

k = -2
