no, it will not have any real zeroes
however, it can have imaginary or complex zeroes

how
since the equation is y⁴+4y²+5=0 i.e y⁴+4y²=-5 but we know that sum of squares of any real numbers can't be negative so it can't have real roots

Since it is a bi-quadartic polynomial it will definitely have atmost 4 zeroes.......
