Explanation Given: The expression is, x 2 12 + x 18 − 1 30 . Theorem used: Addition and Subtraction Theorem/fundamental property of fraction : If a , b , and c are real numbers, then a c + b c = a + b c , where b ≠ 0 . If a , b , and c are real numbers, then a c − b c = a − b c , where b ≠ 0 . Calculation: First, find the LCD of each denominator completely: 12 = 2 ⋅ 2 ⋅ 3 18 = 2 ⋅ 3 ⋅ 3 30 = 2 ⋅ 3 ⋅ 5 Thus, LCD is 2 ⋅ 2 ⋅ 3 ⋅ 3 ⋅ 5 = 180
