Question

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

Answer 1

HeYa❤️...

Used Identity:

$(x + y)(x - y) = x {}^{2} - y {}^{2}$

Solution:

$= (2x + y)(2x - y)(4 x {}^{2} + y {}^{2} ) \\ = (4x{}^{2} - y {}^{2} )(4x {}^{2} + y {}^{2} ) \\ = (4x {}^{2} ) {}^{2} - (y {}^{2} ) {}^{2} \\ = 16x {}^{4} - y {}^{4}$

I hOpe It HeLpS Ya!
