Question

If one zero of the polynomial x^2 -5x + k is -4 , then find the value of k. Find the other zero also.​

Answer 1

Answer:

k=0

Step-by-step explanation:

we know that 1 is a zero of polynomial p(x)= x^2 - x +k

so by putting x=1 we get

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

= 1-1+k

= k

so, p(x)=0

p(1)=0

k =0
