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
