Subtract the Polynomials $$\left( 5 x ^ { 4 } y ^ { 2 } + 7 x ^ { 3 } y + 6 y \right) - \left( 3 x ^ { 4 } y ^ { 2 } + 10 x ^ { 3 } y + 11 y + 9 x \right)$$

question 24

Multiple Choice

Subtract the polynomials. Assume all variable exponents represent whole numbers.
- $$\left( 5 x ^ { 4 } y ^ { 2 } + 7 x ^ { 3 } y + 6 y \right) - \left( 3 x ^ { 4 } y ^ { 2 } + 10 x ^ { 3 } y + 11 y + 9 x \right)$$

• A) \(2 x ^ { 4 } y ^ { 2 } - 3 x ^ { 3 } y - 5 y + 9 x\)
• B) \(8 x ^ { 4 } y ^ { 2 } + 17 x ^ { 3 } y + 17 y + 9 x\)
• C) \(2 x ^ { 4 } y ^ { 2 } + 3 x ^ { 3 } y - 5 y - 9 x\)
• D) \(2 x ^ { 4 } y ^ { 2 } - 3 x ^ { 3 } y - 5 y - 9 x\)
