Question

plz ans this question plz plz tell whether the above equation is quadratic or not ​

Answer 1

Step-by-step explanation:

yes it is a quadratic equation

Answer 2

Answer:

$x - \frac{5}{x} = 3x - 9$

$\frac{ {x}^{2} - 5 }{x} = 3x - 9$

${x}^{2} - 5 = x(3x - 9)$

${x}^{2} - 5 = 3 {x}^{2} - 9x$

${x}^{2} - 3 {x}^{2} + 9x - 5 = 0$

$( - 2 {x}^{2} ) + 9x - 5 = 0$

$2 {x}^{2} - 9x + 5 = 0$

$The \: above \: equation \: is \: quadratic.$
