very \: diffcult \: uestion \\ 9 {x}^{2}  - 6 {b}^{2} x - ( {a}^{4}  -  {b}^{4} ) = 0 \\ 9 {x}^{2}  - 3( {a}^{2}  +  {b}^{2} )x + 3( {a}^{2}  -  {b}^{2} ) x \\  \:  \:  \:  \:  \:  \:  \:  \:    \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: -  ( {a}^{4}  -  {b}^{4} ) \\ 3x( 3x -  {a}^{2} -  {b}^{2}  ) + ( {a}^{2} -  {b}^{2} ) \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   (3x -  {a}^{2}  -  {b}^{2} ) \\ (3x +  {a}^{2} -  {b}^{2}  )(3x -  {a}^{2} -  {b}^{2})   \\  {(3x -  {a}^{2}  -  {b}^{2} })^{2}  \:  \: ans
