Answer:

= 12a-9ab+5b-5x²+4y²-6y

Step-by-step explanation:

12a-9ab+5b-3​-( 5x²-4y²+6y-3)

12a-9ab+5b-3-5x²+4y²-6y+3

(The signs change when the bracket is open. However, the minuend doesn't change, only the signs of the subtrahend changes. The 3s get cancelled because -3+3=0 or 3-3=0).

= 12a-9ab+5b-5x²+4y²-6y
