.
![[2x^4-8x^2y^2-y^4]-[-6x^4-3x^2y^2+5y^4-6x]](https://tex.z-dn.net/?f=%5B2x%5E4-8x%5E2y%5E2-y%5E4%5D-%5B-6x%5E4-3x%5E2y%5E2%2B5y%5E4-6x%5D)
<u>Step 1:</u> Open the bracket, Take note of the signs
![[2x^4-8x^2y^2-y^4]-[-6x^4-3x^2y^2+5y^4-6x]\\2x^4-8x^2y^2-y^4+6x^4+3x^2y^2-5y^4+6x](https://tex.z-dn.net/?f=%5B2x%5E4-8x%5E2y%5E2-y%5E4%5D-%5B-6x%5E4-3x%5E2y%5E2%2B5y%5E4-6x%5D%5C%5C2x%5E4-8x%5E2y%5E2-y%5E4%2B6x%5E4%2B3x%5E2y%5E2-5y%5E4%2B6x)
