The LCD of
Explanation:
LCD is Least Common Divisor.
#(x-4) = (x-4)/1# and#(x+2) = (x+2)/1#
Then the only common divisor (scalar or polynomial) they have is
If you meant to ask what is the LCD of two rational expressions with denominators
#(x-4)(x+2) = x^2-2x-8#
The LCD in this case is the LCM (Least Common Multiple) of the two divisors.
