Question

check whether minus 1 and 2 are the zeros of polynomial p x is equal to x square minus x minus 2​

Answer 1

Answer:

yes both are zeroes

Step-by-step explanation:

p(x)=x²-x-2

x=-1

p(-1)=-1²+1-2

=1+1-2

=2-2

=0

x=2

p(2)= 2²-2-2

=4-2-2

= 4-4

= 0

therefore, both -1 and 2 are zeroes of the polynomial
