Quantity A
Sq root [4(x^4) + 6(x^2) + 9]
Quantity B
(x^2) + 3
The answer says these two are equal.
Why are we eliminating the possibility that the factors may be negative?
i.e. -[(x^2) + 3] * -[(x^2) + 3] also equals quantity A
So, when factoring out, are we expected to eliminate the possibility that the factors may be negative integers?
Thank you!
