Question

(2x-3/x)(2x+3/x) using identity​

Answer 1

Answer:

Step-by-step explanation:

here we can use the identity : a²-b²=(a+b)(a-b)

in this case a=2x  and b= 3/x

I think this much hint is sufficient to solve this question. Go ahead, I am sure you will be able to solve it.

Answer 2

Answer:

$4 {x}^{2} - \frac{9}{ {x}^{2} }$

Step-by-step explanation:

$(2x - \frac{3}{x} )(2x + \frac{3}{x} )$

Usind identity:

$(a - b) \: (a + b) \: = {a}^{2} - {b}^{2}$

${(2x)}^{2} - {( \frac{3}{x}) }^{2}$

$4 {x}^{2} - \frac{9}{ {x}^{2} }$
