Question

If 2x-3/x=5 than find value of 4x^2-9/x^2 =?​

Answer 1

Step-by-step explanation:

$2x - \frac{3}{x} = 5 = >$

on squaring on both sides , we get

${(2x - \frac{3}{x})}^{2} = 25 = > 4 {x}^{2} + \frac{9}{ {x}^{2} } -$

$2 \times 2x \times \frac{3}{x} = 25 = > 4 {x}^{2} + \frac{9}{ {x}^{2}} - 12 =$

$25 = > 4 {x}^{2} + \frac{9}{ {x}^{2}} = 25 + 12 = 37$

Hope it helps you.
