Is a lovely little quadratic function. But since you haven't provided a value for , there are an infinite number of ordered pairs that satisfy the equation.
Now if what you really meant to ask is "What are the roots of ?", in other words, what are the solutions to:
That is another thing altogether. Presuming that is your real question, proceed as follows.
Multiply both sides by
The quadratic does not factor, so use the quadratic formula:
You can do your own arithmetic. Note that the prime factorization of 440 is 2 x 2 x 2 x 5 x 11, so the best you will be able to do with the radical is
