(b) Again we'll use the following steps: Step 1) Find the least common denominator, which is LCD = x ( x + 2). Step 2) Multiply each term of the equation by the LCD to get: x ( x + 2) (3 / x) = x ( x + 2) (10 / ( x +

Finally, we multiplied the factors to find the LCD. 12 = 2 ⋅ 2 ⋅ 3 18 = 2 ⋅ 3 ⋅ 3 LCD = 2 ⋅ 2 ⋅ 3 ⋅ 3 LCD = 36 12 = 2 · 2 · 3 18 = 2 · 3 · 3 LCD = 2 · 2 · 3 · 3 LCD = 36. We do the same thing for rational
