(A) Given equation: $x - \frac{1}{x} = 5$Multiply the entire equation by $x$ to eliminate the denominator:$x(x) - x(\frac{1}{x}) = 5(x)$$x^{2} - 1 = 5x$Rearrange the terms to the standard form $ax^{2} + bx + c = 0$:$x^{2} - 5x - 1 = 0$Here,the highest power (degree) of the variable $x$ is $2$.Since the equation is in the form $ax^{2} + bx + c = 0$ where $a 
eq 0$,it is a quadratic equation.

Examine whether the following equation is quadratic or not: $x - \frac{1}{x} = 5$
