Question

if a and b the zero of the polynomial f(x)=xsqure-x-k such that a-b =9 then find the value of k​

Answer 1

Answer:

k=3

Step-by-step explanation:

the right answer

Answer 2

Answer:

sum of zeroes=a+b=1,

give that,a-b=9

solving above two equation,

a+b=1

a-b=9

2a=10

therefore,a=5

now putting value of a,

5+b=1

b=-4

Now,

product of zeroes=k

a x b=k

5 x-4=k

therefore,k= -20
