Let’s define a substitution to simplify the equation. Let:
Substituting
into the given equation, we have:
Now, this is a standard quadratic equation in
. We can solve it using the quadratic formula:
Here,
,
, and
. Plugging these values into the formula, we get:
Calculating the discriminant:
Thus, we have:
Taking the square root of the discriminant:
Now, substituting back into the quadratic formula:
Calculating the two possible values for
:
Now, we have two cases for
:
and
.
Case 1:
From our substitution, we have:
Applying the quadratic formula again with
,
, and
:
Calculating the two potential solutions:
Case 2:
Now we solve:
Again applying the quadratic formula with
,
, and
:
Again, calculating the two potential solutions:
Combining all the solutions, the real solutions to the initial equation are:
Thus, all solutions (real and imaginary) are:
Real Solutions:
Imaginary Solutions:
There are no imaginary solutions since all derived solutions for are real.
There are no imaginary solutions since all derived solutions for
