Answer:
Step-by-step explanation:
The given equation is:l
Add -2 to both sides of the equation to get:
We factor the LHS by grouping.
We now apply the zero product property to get:
This implies that:
This factor is never equal to zero and has no real solution.
This implies that:
Recall that
We reciprocate both sides to get:
Therefore on the interval
