Explanation The equation given below can be solved with the help of ( a 2 − b 2 ) = ( a + b ) ( a − b ) . 25 x 2 − 169 = 0 . Rewrite the given equation, ( 5 x ) 2 − ( 13 ) 2 = 0 ( 5 x + 13 ) ( 5 x − 13 ) = 0 Use the zero-factor property and consider first part, ( 5 x + 13 ) = 0 Add − 13 to both sides, ( 5 x + 13 − 13 ) = 0 − 13 <
