Answer:
-12x² + 11xy - 2y²
Step-by-step explanation:
To solve this:
You can distribute -3x to 4x
-3x*4x = -12x²
Then distribute the -3x to -y
-3x*-y = 3xy
Distribute the 2y to 4x
2y*4x = 8xy
Distribute the 2y to -y
2y*-y = -2y²
-12x² + 3xy + 8xy - 2y²
Combine like terms and add 3xy to 8xy
Final Answer: -12x² + 3xy + 11xy - 2y²
