2. {8m^2-n^2}-{5n^2+8n-3}
PLZZ HELP

Answer 1

Answer:

1.8xy^2+5x^2+6y^2-3x^2y

2.8m^2-6n^2-8n+3

Step-by-step explanation:

1.5x(x-y^2)+3y(3xy-2y)-xy(3x-4y)

5x^2-5xy^2+9xy^-6y^2-3x^2y+4xy^2

-5xy^2+9xy^2+4xy^2+5x^2+6y^2-3x^2y

8xy^2+5x^2+6y^2-3x^2y

2.{8m^2-n^2}-{5n^2+8n-3}

8m^2-n^2-5n^2-8n+3

8m^2-6n^2-8n+3
