Answer:
Step-by-step explanation:
<u>Given expression</u>
(2x⁴ - 8x²y² - y⁴) - (-6x⁴ - 3x²y² + 5y⁴)
<u>Expand the parenthesis</u>
2x⁴ - 8x²y² - y⁴ + 6x⁴ + 3x²y² - 5y⁴
<u>Move like terms together</u>
2x⁴ + 6x⁴ - y⁴ - 5y⁴ - 8x²y² + 3x²y²
<u />
<u>Combine like terms</u>

<u>Answer:</u>
- Option A (-26x² + 56x - 15) is correct.
<u>Step-by-step explanation:</u>
- [3x(-2x + 7)] - [5(x - 1)(4x - 3)]
- => [-6x² + 21x] - [(5)(x - 1)(4x - 3)]
- => [-6x² + 21x] - [(5x - 5)(4x - 3)]
- => [-6x² + 21x] - [20x² - 15x - 20x + 15]
- => -6x² + 21x - 20x² + 15x + 20x - 15
- => -26x² + 56x - 15
Hence, <u>Option A (-26x² + 56x - 15) is correct.</u>
