We'll impose the constraints of existence of
logarithms.
The first condition
is:
x^2 + 2 > 0
Since
x^2 is always positive for any value of x, the amount:
x^2
+ 2 is also positive, fro any value of x.
The second
condition is:
x^2 - 3x + 5 >
0
We'll calculate the discriminant of the quadratic to
verify if it is negative:
delta = 9 - 20 = -11 <
0
Since delta is negative, the expression x^2 - 3x + 5 is
also positive, fro any value of x.
Conclusion: The solution
of the equtain could be any value of x.
Now, we'll solve
the equation:
log( x^2 + 2 ) = log ( x^2 - 3x +
5)
Since the bases are matching, we'll apply one to one
property:
x^2 + 2 = x^2 - 3x +
5
We'll eliminate and combine like
terms:
3x - 3 = 0
We'll divide
by 3:
x - 1 = 0
x =
1
The solution of the equation is x =
1.
