Question

Check whether the following equations are quadratic?
$x+\frac{1}{x}+x^2,x\ne 0$.

• A. True
• B. False

Answer 1

The correct option is B False

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

Multiplying the equation by ${}^{\prime }{x}^{\prime }$

We have

$x^2+1+x^3$

Rearranging the equation $x^3+x^2+1$

The equation starts with term $x^3$

Hence the given equation cannot be quadratic.
