Solution

The correct option is A True
Let square root of given bi quadratic equation be x2+px+q

We will square the given equation

x4+p2x2+q2+2px3+2pqx+2qx2

Rewriting the terms ;

x4+x3(2p)+x2(p2+2q)+x(2pq)+q2

Comparing the above equation with given equation ;

q2=16
q=4

2pq=24
p=3

p=3 and q=4

square root =x2+3x+4

Hence, the given statement is true.
