Question

is a zero is the polynomial p(x)=(x+5) (x-2)​

Answer 1

2 is a zero of this polynomial, there can be more also

Answer 2

Answer:

You seem to be asking if the respective values of x are the zeroes of the polynomial.

Multiplying x+5 and x-2

We get x²+-2x+5x-10

x²+3x-10

p(x)= x²+3x-10

p(-5)= (-5)²+3(-5)-10

= 25-15-10= 0

p(2)=2²+3(2)-10

= 4+6-10

=0

Therefore, yes, they are the zeroes of the Polynomial.

Hope this helps.
