Question

verify whether 2 is 0 zero of polynomial x^3+4x^2-3x-18​

Answer 1

Answer:

Given - polynomial x^3+4x^2-3x-18

To find - whether 2 is zero of a polynomial or not.

Solution -

putting p(2) in polynomial

p(x) = x^3+4x^2-3x-18

p(2) = 2^3 + 4(2)^2 - 3(2)- 18

p(2) = 8 + 16 - 6- 18

p(2) = 24 - 24

p(2) = 0

hence , proved

it is a zero of the polynomial .

note- A zero of a polynomial is that value in no. through which the whole polynomial becomes zero.
