Vedclass · Answer

(B) quadratic equation in the variable $x$ is an equation of the form $ax^{2} + bx + c = 0$,where $a, b, c$ are real numbers and $a 
eq 0$. In the given equation $x^{2} + 5\sqrt{x} - 7 = 0$,the term $5\sqrt{x}$ can be written as $5x^{1/2}$. Since the exponent of the variable $x$ is $1/2$,which is not a non-negative integer,this equation is not a polynomial equation of degree $2$. Therefore,it is not a quadratic equation.

Examine whether the following equation is quadratic or not: $x^{2} + 5\sqrt{x} - 7 = 0$.
