Answer:

Quadratic equations are generally found in the form of .ax^{2} + bx + c = 0

The equation x^{2} + 2\sqrt{x} - 3 = 0 is not in the form of ax^{2} + bx + c = 0

Let us compare these two..

Since both equations are equal to 0, we can write x^{2} + 2\sqrt{x} - 3 = ax^{2} + bx + c  

The first terms are x^{2} and ax^{2}. This will be correct when a = 1

The second terms are 2\sqrt{x} and bx. This will not be equal even when b = 2 because \sqrt{x} cannot be used as the variable in a quadratic equation.

The third terms are -3 and c. This will be correct when c = -3.

So, since quadratic equations cannot have variables as square roots, the given equation is not a quadratic equation.

Hope this helped!
