Question

Factorise
(3xsquare+4ysquare)(3xsquare-4ysquare)​

Answer 1

Step-by-step explanation:

$(3 {x}^{2} + 4 {y}^{2} )(3 {x}^{2} - 4 {y}^{2} )$

$= ( {3 {x}^{2} })^{2} - ( {4 {y}^{2} })^{2}$

$= 9 {x}^{4} - 16 {y}^{4}$

Answer 2

$\huge\mathbb\red {۝ Answer۝ }$

$\mathrm\pink{=(3x²+4y²)(3x²-4y²)}$

$\mathrm\pink{=(3x²)²-(4y)²}$

$\mathrm\pink{=9x⁴-16y²}$
