Question

Which of the following are quadratic equation in x?

`x + 2/x = x^2`

Answer 1

Given: `x + 2/x = x^2`

Step-wise calculation:

1. Note x ≠ 0 (denominator).

2. Multiply both sides by x:

x² + 2 = x³

3. Rearrange to one side:

x³ – x² – 2 = 0

The equation simplifies to a cubic polynomial (degree 3), not a quadratic (degree 2).

Therefore, `x + 2/x = x^2` is not a quadratic equation in x.
