Answer 2

HERE IS UR ANSWER DEAR,

let x=0,

p(0) = 2(0)²+5(0)+3

= 3

which is not equal to zero

therefore it is not a zero of the polynomial

let x=1 ,

p(1)= 2(1)²+5(1)+3

= 2 + 5+ 3

= 10

which is not equal to zero

therefore it is not a zero of the polynomial

let x= -1

p(-1) = 2(-1)²+5(-1)+3

= 2 -5 +3

= 0

it is equal to zero

hence ,

x= -1

-1 is the zero of the polynomial !!
