The center of the circle that circumscribe about DABC is
.
A circle can be modelled after a expression of the form:
(1)
We can determine all coefficients by knowing three <em>distinct</em> points on plane.
If we know that
,
and
, then the solution of the system of linear equations is:
(2)
(3)
(4)

Now we proceed to <em>complete</em> squares and factor each resulting perfect square trinomial in order to determine the coordinates of the center of the circle:

Answer:

Step-by-step explanation:
Consider the equation

Substitute

into the equation:

This is quadratic equation, where

Hence,

Now, use the substitution again:
1. When
then

2. When
then

This equation has no solutions, because the range of
is
and 3>1.
34 because it's a bigger number and -$67 is lower
