Question

find the value of k if x minus 1 is a factor of p(x)=x squared plus x plus k​

Answer 1

Answer:

put x= 1 in equation u will get k

Step-by-step explanation:

(1)^2+1+k=0

k=-1

.. . . . . . . . . .

Answer 2

Answer:

p(X)=x^2+x+k

x-1 is factor

therefore,X=1

p(1)=(1)^2+1+k=0

=1+1+k=0

=2+k=0

k=-2
