To simplify the expression (5xy + 2x^2 - xy - 3y^2), we first combine like terms. The terms involving (xy) are (5xy - xy), which simplifies to (4xy). Therefore, the simplified expression is (2x^2 + 4xy - 3y^2).
To simplify the expression (-3x^2 + 2y^2 + 5xy - 2y + 5x^2 - 3y^2), we combine like terms. The (x^2) terms combine to (2x^2) (from (-3x^2 + 5x^2)), the (y^2) terms combine to (-y^2) (from (2y^2 - 3y^2)), and there is one (xy) term, which is (5xy). Therefore, the simplified expression is (2x^2 - y^2 + 5xy).

6xy(2x2 - 3y)
5xy+4=9 is the problem, right? 5xy+4=9. Now subtract the 4 from both sides. 5xy=5. Ok, then, that looks less scary. Now, divide both sides by 5, to get xy=1. Hmm, a lot simpler. Now, divide both sides by x to get y by itself. So, y=1/x. Alright. That's your line! No, its not a straight line. There is a vertical asymptote where x=0, and the two segments aren't straight. But that's a simpler form of the equation. Hope that helped!
The expression ( xy - 2 ) is already in its simplest form. It represents the product of ( x ) and ( y ) subtracted by 2. There are no like terms to combine or factors to simplify further.
(2x - 3y)(x + y)
(-5xy):(-xy)=
xy(7+2y-3x)-6xy
3, since the degree of a polynomial is equivalent to its highest power.
1xy
1 whenever there is a coefficient of one then it is not written but "understood"
To simplify the expression (-3x^2 + 2y^2 + 5xy - 2y + 5x^2 - 3y^2), we combine like terms.

Therefore, the simplified expression is (2x^2 - y^2 + 5xy).
If you mean, "x-3y = 12", then xy = 3y2 + 12y.
