Question

find the integral zeros of the polynomial 2x^3+5x^2-5x-1

Answer 1

HEY MATE HERE IS YOUR ANSWER

___________________________

Given : P(x) = 0

Therefore,

P (0) means value of x will be zero. Of we put this in given equation if it comes 0 then it is a polynomial of zero.

____________________move to question

$= > p(x) = 2 {x}^{3} + 5 {x}^{2} - 5x - 1$
$= > p(0) = 2(0 {)}^{3} + 5(0 {)}^{2} - 5(0) + 1$
$= > 0 - 0 - 0 - 1$

$= > - 1$

➡️$\huge \bold {\boxed {- 1 ≠ 0}}$

Therefore it is not a zero of polynomial.
