Step-by-step explanation:
The given equation is
To factor this expression, we can change variables to make easier to see the solution.
Applying the change, we have
Now, you can observe that to factor this expression, we just need to find two number which product is 14 and which difference is 5, such numbers are 7 and 2.
However, remember that
, so
Applying the zero property, we have
As you can see, the equation has two real solutions and two complex solutions.
Therefore, the right answer is the last choice.
