question 68

Multiple Choice

Subtract the polynomials. Assume all variable exponents represent whole numbers.
- $$\left( 4 x ^ { 4 } + 5 x y - y ^ { 3 } \right) - \left( x ^ { 4 } + 3 x y + 5 y ^ { 3 } \right)$$

• A) \(4 x ^ { 4 } + 2 x y - 6 y ^ { 3 }\)
• B) \(3 x ^ { 4 } + 2 x y - 6 y ^ { 3 }\)
• C) \(3 x ^ { 4 } + 2 x y - 4 y ^ { 3 }\)
• D) \(5 x ^ { 4 } + 12 x y + 4 y ^ { 3 }\)
