Question

The value of k if x-1 is factor of x²+x - k is

Answer 1

Answer:

x-1 is the factor of x²+x-k

zeroes of x-1 is

x-1 = 0

x= 1

put the value of x in equation x² + x - k

(1)²+(1) - k

= 1+1-k

=2-k

zeroes of 2-k is

2-k=0

-k =-2

so,

k=2

Answer 2

Answer:value of K = 2

Step-by-step explanation:

x -1=0, therefore x=1

Putting the value of x in equation p(x) the answer comes 2
