Question

verify whether the following are
zeroes of the polynomial indicated against them
p(x) = (x + 1) (x-2), at x=-1 ,2​

Answer 1

Step-by-step explanation:

putting the values in x

-1+1)(-1-2)

0(-3)

0 no

(2+1)(2-2)

3(0)

0 hence no one is the zero of the polynomial

Answer 2

Step-by-step explanation:

P(x)=(x + 1) (x-2)

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

put x=1

p(1)=1-1

p(1)=0
