I have been presented with the following equation:
According to the text, the solution is 6. I have been unable to reach this answer.
Here is the method I've used:
The LCD of is .
I multiply each side of the equation by the LCD and get the following:
which is then simplified into
From there I try to factor the left side of the equation, but it turns out being prime after using the FOIL method.
Yet somehow my textbook lists the solution as 6. What am I doing wrong?
I encounter the same situation in another similar equation who's solution set is supposed to be 2, 3 :
Again, I determine the LCD is and multiply each side by this.
I once again try to factor, but just as before
The solution set is supposedly 2, 3. Grrrr...
