x + 2 - (12 / x + 3) / x - 5 + (16 / x + 3)
Would the LCD be x(x + 3)? If so, I just multiply the numerator and denominator of this complex fraction by x(x + 3) to find the answer, correct?
The LCD in both the top and bottom will be (x+3). Think of the non-fraction numbers as , this will help you see how to evaluate their LCD
So you will have a fraction over a fraction, with LCD both (x+3). Then, just multiply the top by the reciprocal of the bottom to get rid of the big fraction. This will leave you with a new fraction, which you can multiply out giving you your final LCD
