Why is this not a quadratic equation??Pls solve this​

Answer 1

Answer:

$ax {}^{2} + bx + c \: \: is \: the \: general \: form \: of \: quadratic \: equation$

$x {}^{2} + \frac{1}{x {}^{2} } = 5$

$2x {}^{2} + 1 = 5x {}^{2}$

$3x {}^{2} - 1 = 0$

$there \: is \: no \: x \: term \:$

$so \: it \: is \: not \: quadratic \: equation$
