Yes, they could. If x+a < 0 and y+b <0.
We are not here to do your homework for you.
Half of XY...
Anything with a negative (-) x value and positive (+) y value is in the second quadrant.
On an XY graph, the X axis and Y axis create four separate areas. Each one is a quadrant.
Factor by grouping. x2y - xyb - abx + ab2 The first two can factor out an xy, so xy(x - b) The second two can factor out a -ab, so -ab(x - b) and we have xy(x - b) - ab(x - b) Since what is inside the parentheses is alike, we can be assured that we have factored correctly and now continue to group: ANS: (x - b)(xy - ab)
The perpendicular bisector of the line XY will meet it at its midpoint at right angles.
Quadrant II (Quadrant 2) is the region of the coordinate plane (xy-plane, a graph) that is above the x-axis and to the left of the y-axis. In this quadrant, all x values are positive and all y values are negative.

Z is halfway between X and Y.
at the origin
All ordered pairs, (a,b) such that a > 0 and b > 0
x2y + axy + abx + a2b Factor by grouping. xy(x + a) + ab(x + a) (xy + ab)(x + a)
