Hi Mate!!!
{ ( 2x)² - (3 / x )² } = { 2x - (3/x) } { 2x + (3/x) }
= { 2x + (3/x) } × ( 5 )
Now we will find { 2x +(3/x) }
{2x + (3/x) } = √[{ 2x - 3/x } ² +4(6)]
{2x + (3/x) }. = √[ 25 +24]
= 7
So,. 4x² +( 9/x²). = 5 × 7
4x² + (9 / x²) = 35 But none of the options out of three matches.
Hey, Mate. if 37 is right ans. then question should be like this. 4x² + 9/x²
We can solve this as well like
4x² + 9/x². =. ( 2x- 3/x)² + 2 ( 6)
= 25 + 12
=>. 4x² + 9/x². = 37.
Have a nice day
