It\'s all worked out, but I\'m still very confused by the steps they took to get each part. Like why multiply everything by (x^2 + 9) and then in the next step, how did they end up with those answers? I\'m just very confused. Solution they just multiplide (x^2 + 9) for simpification LIKE EXAMPLE eq 2+3=5 if we multify both sides with 2 (2+3)2=5*2 10=10 equality not changed ,,,like we use this in mathematics after solving eq they got X parameters and they cheked in original eq.
