Question

is polynomial y^4 + 4 y^2 + 5 have zeroes or not? if yes find the zeroes

Answer 1

Answer:

This polynomial not have zero

Step-by-step explanation:

Y4+4y2+5=y4+4y2+4 +1 =(y2+2)2+1 The first term being square,it will be equal to zero or greater than zero. Therefore (y2+2)2+1 will not be zero for any value of y. Therefore given polynomial have no zeroes.

Answer 2

Answer:

this will have no zeros.

Step-by-step explanation:

Y4+4y2+5=y4+4y2+4 +1 =(y2+2)2+1 The first term being square,it will be equal to zero or greater than zero. Therefore (y2+2)2+1 will not be zero for any value of y. Therefore given polynomial have no zeroes.
