Answer:
2x^{2} - y^{2} +5xy - 2y
A) 4 terms
B) 0 negatives
Step-by-step explanation:
Combine the like terms
So -3x squared + 5x squared = 2x squared
2y squared - 3y squared = -1y squared
There is only one term with 5xy so you leave it as it is
There is only one term with 2y so you leave it as it is
Now put this in an equation and use the negative and positive signs as addition or subtraction signs.
So it looks like:
2x^{2} - y^{2} +5xy - 2y

Answer: number 2
cuz its the only one that makes sense
(x-3)^2, as x-3 is repeated twice
Im not sure if you wrote this wrong because (x+y)2 does equal x2+y2. An example would be if x equals 3 and y equals 4 (3+4)2=(3)2+(4)2 (7)2=6+8 14=14.
