Find the difference of the two polynomials.

Set: (7y^2 + 6xy) - (-2xy + 3)

Since there are 2 negatives, they cancel out and become a positive or addition sign.

Thus, the new equation is: (7y^2 + 6xy) + (2xy + 3)

Solve:

(7y^2 + 6xy) + (2xy + 3)

Combine like terms.

7y^2 + 8xy + 3

Solution:

7y^2 + 8xy + 3

(7y² + 6xy) - (-2xy + 3)

⇒ (-1 * -2xy) + (-1 * 3) = 2xy - 3

7y² + 6xy + 2xy - 3

7y² + 8xy - 3  Choice B.
