Which of the following are quadratic equations in x?

2x + 3)(3x + 2) = 6(x - 1)(x - 2)

The given (2x + 3)(3x + 2) = 6(x - 1)(x - 2)equation is not a quadratic equation.

Explanation - Given (2x + 3)(3x + 2) = 6(x - 1)(x - 2)

On getting reduced it becomes

It is not in the form (a ≠ 0, a, b, c are real numbers)
