Question
Identify the least common denominator of each group of rational expression, and rewrite each as an equivalent rational expression with the LCD as its denominator.$\frac{8}{d}, \frac{2}{d-4}$
Step 1
The denominators of the two expressions are $d$ and $d-4$. Since these two expressions cannot be factored any further without knowing the exact value of $d$, we consider them as their own unique factors. Show more…
