bbb1996 has presented this problem correctly, except that the fractions are a bit difficult to read.  He/she is to combine the two fractions through subtraction and to simplify the resulting equation.

bbb:  What is the LCD (lowest common denominator) of the two fractions?

i am thinking its the x

mathmale · Answer

The x could not be it, because x alone does not include that 2 you see in the other denominator.  The LCD MUST include as a factor every distinct quantity in all of the denominators.
