Answer:


(2x^(4) -8x^(2) y^(2) - y^(4) ) - (-6x^(4) - 3x^(2) y^(2) + 5y^(4) )

=
2x^(4) - 8x^(2) y^(2) - y^(4) + 6x^(4) + 3x^(2) y^(2) - 5y^(4)

=
8x^(4) - 5x^(2) y^(2) - 6y^(4)

hope this helps!!!!

Answer:
\Large\boxed{8x^4-5x^2y^2-6y^4}

Explanation:

Given expression

(2x⁴ - 8x²y² - y⁴) - (-6x⁴ - 3x²y² + 5y⁴)

Expand the parenthesis

2x⁴ - 8x²y² - y⁴ + 6x⁴ + 3x²y² - 5y⁴

Move like terms together

2x⁴ + 6x⁴ - y⁴ - 5y⁴ - 8x²y² + 3x²y²

Combine like terms


\Large\boxed{8x^4-5x^2y^2-6y^4}

Hope this helps!! :)
