    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
