This is an irreducible quadratic.
The constant, by multiplying the first and last terms. In this equation, it is found like this:
\(9*-10=-90\)
Now, in order for it to be factored, two factors of \(-90\) must be equal to \(-5\).
Since there are no two factors of \(-90\) that equal \(-5\), this is an irreducible quadratic.
