Question

for what value of 1 is a zero of the polynomial x^2+x+k​

Answer 1

given

one of the polynomial is 1

polynomial =

x^2-x+k

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

1-1+k=0

=》 k=0

Answer 2

Answer:

p(x)=x²+x+k

p(0)=0²+0+k

p(0)=0+0+k

p(0)=0

=0

p(x)=x²+x+k

p(1)=1²+1+k

p(1)=2²+k

=2²+k

p(x)=x²+x+k

p(2)=2²+2+k

p(2)=4²+k

=4²+k

no one should match this is wrong

hope it's help you
