Answer:
The roots for
are
and
, respectively.
Explanation:
A root is a value of
so that
. Let suppose that function is the consequence of the subtraction between two functions, that is:
(1)
If we know that
,
and
, then we have the following identity:

We can estimate graphically the roots of
by graphing the following system:
(2)
(3)
Where roots are the points in which functions find each other.
With the help of a graphing, we estimate two solutions:
,
