2. -6y - 1

3. -10x - 2y - 7

4. -2x - 6

5. 2x - 12y - 4

Step-by-step explanation:

1. 2x+3y-6-4x+3y+2

(2x-4x) + (3y+3y) + (-6+2)

-2x + 6y - 4

2. 4x-3y-3-4x-3y+2

(4x-4x) + (-3y-3y) + (-3+2)

-6y - 1

3. -8x+2y-8-2x-4y+1

(-8x-2x) + (2y-4y) + (-8+1)

-10x - 2y - 7

4. -X+Y-3-X-Y-3

(-x-x) + (y-y) + (-3-3)

-2x - 6

5. 4x-8y-6-2x+4y+2

(4x-2x) + (-8y-4x) + (-6+2)

2x - 12y - 4

See explanation below.

Step-by-step explanation:

Part A:

(i). They both correct because they could have a third degree polynomial that crosses the x-axis 3 times.

(ii). To find the zero's of the first one, set function equal to zero and use zero factor principle given as:

So, we have:
