Polynominals ???
I need to find the missing polynominal. Can someone explain how to do that. I know the answer is x^2-6xy-1... but how to get it?
(3x^2+2xy-1)+(x^2+xy+5)+(?)=5x^2-3xy+3

Your question was cut off so I will guess it was
(3x^2+2xy-1)+(x^2+xy+5)+(?)= 5x^2 -9xy + 3
What you do is combine the like terms on the left:
4x^2 + 3xy + 4 + (?) = 5x^2 - 3xy + 3
Then add the opposite of each part on the left to both sides to leave only the ? and puting the like terms together to make them easier to combine
(5x^2 - 4x^2) - 3xy - 3xy + 3 - 4
so you'd get that answer

Add
4x^2 + 3xy + 4 + ? = x^2 - 6xy - 1
? = -3x^2 - 9xy - 5
Subtract left side and leave ? by itself

Please write the full question. After 5x, there is nothing?
