21-7y+3x-xy7(3-y)+x(3-y)
Can you help me find the value x & Y 3x + 7y = 5 5x-2y = -19
(1 - x4y4) = (1 + x2y2)*(1 - x2y2) = (1 + x2y2)*(1 + xy)*(1 - xy)
4x-y2=2xy 2x ? y5 if its plus its 7 xy
It is not possible to give a sensible answer to this question. The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers (or expressions). Although it may not appear so, xyz + xy is only one expression.
xy(3x - 2y)(2x + 3y)
(y - 3)(x + 2y)
2+2y+x+xy=(x+2)(y+1)
(3x+2y)*(5x-3y) =3x*5x + 3x*(-3y) + 2y*5x + 2y*(-3y) [This is sometimes called the FOIL method - You multiply the First members of each bracket, then the Outers, Inners, Lasts] = 15x2 - 9xy + 10xy - 6y2 = 15x2 + xy - 6y2
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "equals", "squared". There are no symbols between xy and 3x, nor between 2y and 10.

if you take a factor of (Y) you end up with Y(X+5Z-2).
2 plus 2y plus x plus x y = 2 plus3y plus 2x (find how many X's there are and add them together and ten Y's and then single numbers)
If that's xy + x^2y, it factors to xy(x + 1) If it's something else, please re-submit your question with any plus signs written out.
xy(7+2y-3x)-6xy
xy(x - 2y)(x + 2y)
