Question

x^2 - 9 / x^2 + 5 = -5/9
solve the equation​

Answer 1

Answer:

x^2 -9/x^2 +5 = -5/9

9x^2 - 81 = -5x^2 - 25

14x^2 = 56

x^2 56/14

x^2 = 4

x= 2

Answer 2

Step-by-step explanation:

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

$= > \frac{ {x}^{4} - 9 + 5 {x}^{2} }{ {x}^{2} } = - \frac{5}{9}$

$= > 9 {x}^{4} - 81 + 45 {x}^{2} = - 5 {x}^{2}$

$= > 9 {x}^{4} + 45 {x}^{2} + 5 {x}^{2} - 81$

$= > 9 {x}^{4} + 50 {x}^{2} - 81$
