question 23

Multiple Choice

Add the polynomials. Assume all variable exponents represent whole numbers.
- $$\left( 12 x ^ { 2 } y - 10 x y + 11 \right) + \left( - 11 x ^ { 2 } y + 4 x y - 6 \right)$$

• A) \(x ^ { 2 } y - 6 x y + 5\)
• B) \(23 x ^ { 2 } y + 14 x y + 17\)
• C) \(- x ^ { 2 } y - 14 x y + 17\)
• D) \(- 6 x ^ { 3 } y ^ { 2 } + 5\)
