Answer:
.
Step-by-step explanation:
Fact:
.
In other words, , the difference of two squares in the form
and
, could be factorized into
.
In this question, the expression is the difference between two terms:
and
.
is the square of
. That is:
.
- On the other hand,
.
Hence:
.
Apply the fact that to factorize this expression. (In this case,
whereas
.)
.
When the squared terms are of different signs, the equation generally describes a hyperbola. This one has its vertices at x=±30, so the parameters of interest are
domain: (-∞, -30] ∪ [30, ∞)
range: (-∞, ∞)
domain: (-∞, -30] ∪ [30, ∞)
