Question

find the value of k if x-1 is a factor of p(x) =kx^2-5x+2k​

Answer 1

Answer:

If x+1 is a factor of the polynomial 2x^(2)+kx, then the value of k is. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams. Hence , the value of k is 2

Answer 2

Answer:

p(x) = kx²-5x+2k

let x-1 = 0

x = 0+1

x = 1

p(1) = k(1) ²-5×1 +2k

= k-5+2k

= 3k-5

since x-1 is a factor of p(x)

p(1) = 0

3k-5 = 0

3k = 5

k = 5/3
