You sort-of found two ordered pairs.
You found that for , . That gives you the ordered pair (x,y)=(0,1).
That's what they mean by an ordered pair: (value of x, value of y).
You also found that for . That gives you the ordered pair (-1/5, 0).
If you have to enter your answers online, be aware that computers are sometimes finicky. They may recognize (0, 1), with a space after the comma, as right, but consider (0,1), without a space, wrong. It's not the computer's fault; it's lack of imagination on the part of whoever was deciding what was a right answer. (My youngest son had that problem with his online classes sometimes).

Rewrite this as:

To get y = 1 as you did, you must have let x = 0, why? because:

So the ordered pair is: (0, 1)
And if you solved this quadratic equation, you would get:
Set y = 0.
Factor the left side.
so...
which is a double solution.
So when , , the ordered pair would be: (,)
But note that there is an infinite number of ordered pairs that satisfy this equation.
