Explanation Concept: Distributive property, a b + a c = a ( b + c ) . Multiply both sides of the equation by the LCD of all rational expressions in the equation. a 2 - b 2 = a + b ( a - b ) Calculation: To solve a 9 a 2 - 1 + 2 6 a - 2 Based on the above concept, Substitute a = 3 a and b = 1 in a 2 - b 2 = a + b a - b ( 3 a ) 2 - 1 2 = 3 a + 1 ( 3 a - 1 ) Replace 9 a 2 - 1 with 3 a + 1 ( 3 a - 1 ) . By distributive property, 6 a - 2 = 2 ( 3 a - 1 ) a 3 a + 1 ( 3 a - 1 ) + 2 2 ( 3 a - 1 ) Multiply and divide by 2 3 a + 1 ( 3 a - 1 ) , 2 3 a + 1 3 a - 1 2 3 a + 1 3 a - 1 a 3 a + 1 3 a - 1 + 2 2 3 a - 1 2 3 a + 1 3 a - 1
