Question

.Verify whether the indicated numbers are zeroes of their corresponding
polynomials.

p(x) = 3x3 + 7x2 – 2x – 1 ;  x = 2 and -1
It's urgent!!​

Answer 1

Answer:

given equation are

i) p(x)=3x^3-7x^2-2x-1. (putting x=2)

=3(2)^3-7(2)^2-2(2)-1

=3(8)-7(4)-2(2)-1

=24-28-4-1= -29

ii)p(x)=3x^3-7x^2-2x-1. (Putting x=1)

=3(1)^3-7(1)^2-2(1)-1

=3(1)-7(1)-2(1)-1

=3-7-2-1= -7

so, your answer are -29 and -7
