The discriminant is only
b%5E2-4ac
from above, we get
10%5E2-4%2A1%2A%28-25%29
which is
100+%2B+100
or
200
since this is positive you will have 2 real solutions.

For a quadratic equation in standard form, namely:



the discriminant, , is given by:



Two real and unequal roots. If the discriminant is a perfect square, the roots are rational. Otherwise not.

One real root with a multiplicity of two. That is to say that the trinomial is a perfect square and has two identical factors.

A conjugate pair of complex roots of the form where is the imaginary number defined by
