Question

Choose the best possible option.
$x^2+\frac{1}{4x^2}-8=0$ is a quadratic equation.

• A. Yes
• B. No
• C. Can't predict
• D. None

Answer 1

The correct option is B No

$x^2+\frac{1}{4x^2}-8=0$
$\frac{4x^4+1-8\times 4x^2}{4x^2}=0$
$4x^4+1-32x^2=0$
The degree of the equation is 4
$\therefore x^2+\frac{1}{4x^2}-8=0$ is not a quadratic equation
