$\bold{ GIVEN}$:$9 {x}^{2} - 6 {a}^{2} x + ( {a}^{4} - {b}^{4} ) = 0$

$⟹</p><p>9 {x}^{2} - 6 {a}^{2} x + ( {a}^{4} - {b}^{4} ) = 0$

$⟹</p><p>9 {x}^{2} - 6 {a}^{2} x + ( {a}^{2} + {b}^{2} )( {a}^{2} - {b}^{2} ) = 0$

$⟹</p><p>\bold{Here\:product \:of \:coefficient \:of \:x \:square \:and \:the \:constant \:term}$

$= 9( {a}^{2} + {b}^{2} )( {a}^{2} - {b}^{2} )$

$= (3 {a}^{2} + 3 {b}^{2} )(3 {a}^{2} - 3 {b}^{2} )$

$so \: that \: 3 {a}^{2} + 3 {b}^{2} + 3 {a}^{2} - 3 {b}^{2} = 6 {a}^{2}$

$⟹</p><p>\bold{∴ The\: given\: quadratic \:equation\: can\: be\: written\: as }$

$⟹</p><p>9 {x}^{2} - (3( {a}^{2} + {b}^{2} ) + 3( {a}^{2} - {b}^{2} ))x + ( {a}^{2} + {b}^{2} )( {a}^{2} - {b}^{2} ) = 0$

$⟹</p><p>9 {x}^{2} - 3x( {a}^{2} + {b}^{2} ) - 3x( {a}^{2} - {b}^{2} ) + ( {a}^{2} + {b}^{2} )( {a}^{2} - {b}^{2} ) = 0$

$⟹</p><p>3x(3x - {a}^{2} - {b}^{2} ) - ( {a}^{2} - {b}^{2} )(3x - {a}^{2} - {b}^{2} ) = 0$

$⟹</p><p>( 3x - {a}^{2} - {b}^{2} )(3x - {a}^{2} + {b}^{2} ) = 0$

$⟹</p><p>3x - {a}^{2} - {b}^{2} = 0$

$⟹</p><p>3x - {a}^{2} + {b}^{2} = 0$

$⟹</p><p>3x = {a}^{2} + {b}^{2}$

$⟹</p><p>3x = {a}^{2} - {b}^{2}$

$⟹</p><p>x = \frac{ {a}^{2} + {b}^{2} }{3}$

$⟹</p><p> = \frac{ {a}^{2} - {b}^{2} }{3}$

$\bold{∴The\: solution\: of \:given\: quadratic \:equation\: are:-}$

$\bold{\red{ \frac{ {a}^{2} + {b}^{2} }{3} \: and \: \frac{ {a}^{2} - {b}^{2} }{3} }}$
