$= > (3c {}^{2} - 4d {}^{2} )(4c {}^{2} - 3d {}^{2} )$

$= > 3c {}^{2} (4c {}^{2} - 3d {}^{2} ) - 4d {}^{2} (4c {}^{2} - 3d {}^{2} )$

$= > 12c {}^{4} - 9c {}^{2} d {}^{2} - 16c {}^{2} d {}^{2} + 12d {}^{4}$

$= > 12c {}^{4} - 25c {}^{2}d {}^{2} + 12d {}^{2}$

$\huge{\underline{\underline{\tt{\blue{Question}}}}}$

$\red{(3c² - 4 d²)( 4c² - 3 d²)}$

$\huge{\underline{\underline{\tt{\green{Solution}}}}}$

$\orange{=>(3c² - 4 d²)( 4c² -3 d²)}$

$\orange{=>3c² ( 4c² - 3 d²)-4d²(4c²-3d²)}$

$\orange{=>(12c⁴-9c²d²-16c²d²+12d⁴)}$

$\orange{=>(12c⁴-25c²d²+12d⁴)}$
