Tutorial ExerciseRewrite each of the following rational expressions in terms of their least common denominator.x + 2x - 7Step 1 of 2Identify the least common denominator of the two given rational expressions.The two given rational expressions each have binomial denominators. The denominators are (x + 2) and(x - 7). Recall that the least common denominator, or LCD, of two rational expressions is given by the LCMof their denominators.The least common multiple, or LCM, of two binomials with no common factors is their product. Thus, the LCMof the denominators (x + 2) and (x - 7) is given by the following expression.(x + 2)(Thus, the LCD of the given rational expressions is given by the following.(x+2)Submit Skip (you cannot come back).
