2. LCD
One way to solve rational equations is to multiply each side by the Least Common Denominator (LCD)
EX 1: Solve 45 = 1700/(d-33)

3. Solve the Following
EX 2: x+((x2–5)/(x2–1))=(x2+x+2)/(x+1)

4. Solve Some More EX 3: 10 + 2n-5 2n+5 n2–1 n-1 n+1 EX 4: 2x - 2x 1

5. Inequalities Now! EX 5: ((x-2)(x-1))/((x-3)(x-4))<0
Start by marking the zeros on a number line, then check all the intervals
EX 6: Solve
> 3
