of the graph of the function are solutions to the quadratic equation. Solutions are sometimes called zeros of the quadratic function or roots of the quadratic equation.
When graphed, a quadratic function forms a special curve called a
the related equation has no real solutions. However, the related equation does have two imaginary solutions. Imaginarynumbers can be written in the form
a
+
b
i
,
where
a
and
b
are real numbers,
b
≠
0
,
and
i
=

1
.
You can use some of the methods below to find imaginary solutions.
