Question

Factorise each of the following: (3x – 4y)⁴ – x⁴ using identites​

Answer 1

Step-by-step explanation:

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

==> $[(3x-4y)^{2}+x^{2}][(3x-4y+x)(3x-4y-x)]=[(3x-4y)^{2}+x^{2}][(4x-4y)(2x-4y)]$

==>$[(3x-4y)^{2}+x^{2}][4(x-y)2(x-2y)]=[(3x-4y)^{2}+x^{2}][8(x-y)(x-2y)]$

I hope that u can manage from here.

Thank u.
