Use the discriminant. For your equation: a = 7, b = -8, and c = 0.
For any quadratic polynomial equation of the form:
Find the Discriminant,
and evaluate the nature of the roots as follows:
No calculation quick look: If the signs on
and
are opposite, then
guaranteed.
Two real and unequal roots. If
is a perfect square, the quadratic factors over

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
