Question

If x - 1 is a factor of the following polynomial, then the value of k is 5² +​

Answer 1

Answer:

k=2

Step-by-step explanation:

p(x) = 2x^2 + kx

if x + 1 is the factor then the value of x,

x + 1 = 0

x = -1

we have got the value as -1 of x,

so now we will substitute the value of x to p(x)

p(x) = 2(-1^2)+k*-1

p(x) = 2 - k =0

        -k = -2

        k = 2
