+bx+c=0

Therefore,the given equation is not a quadratic equati

Answer 2

Answer:

it has been given that, x2+1x2=5Now, solving the above equation further we get, x2+1x2=5⇒ x4 + 1 = 5x2⇒ x4 − 5x2 + 1 = 0Now, the above equation clearly does not represent a quadratic equation of the form ax2 + bx + c = 0, because x4 − 5x2 + 1 = 0 is a polynomial of degree 4.Hence, the above equation is not a quadratic equation.
