Question

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

Answer 1

Answer:

Step-by-step explanation:

here we have an advantage ar there is multiplication so if one term is zero then the whole thing will be zero

so let us take p(-5)      (as -5 +5 =0)

p(-5)=(-5 +5)(-5 -2)

=0 x -7

=0

we can have an other value that is 2

as p(2)=(2+5)(2-2)

=7 x 0

=0

so we have two sol. : -5,2
