Start with the given equation

Let's test the first solution (0,0):

Plug in and

Simplify. Since the two sides of the equation are equal, this means (0,0) is a solution to

-------Now lets test another solution-------

Let's test the second solution (-2,10):

Plug in and

Simplify. Since the two sides of the equation are not equal, this means (-2,10) is not a solution to

-------Now lets test another solution-------

Let's test the third solution (-1,-5):

Plug in and

Simplify. Since the two sides of the equation are equal, this means (-1,-5) is a solution to

-------Now lets test another solution-------

Let's test the fourth solution (-3,9):

Plug in and

Simplify. Since the two sides of the equation are not equal, this means (-3,9) is not a solution to

==========================
Answer:
So the following ordered pairs are solutions to

(0,0) and (-1,-5)
