Answer:
Step-by-step explanation:
So we have the expression:
And we wish to factor it.
First, let's make a substitution. Let's let u be equal to x². Therefore, our expression is now:
This is a technique called quadratic u-substitution. Now, we can factor in this form.
We can use the numbers -3 and -2. So:
For the first two terms, factor out a u.
For the last two terms, factor out a -3. So:
Grouping:
Now, substitute back the x² for u:
And this is the simplest form.
And we're done!
Its a reflection over an x-axis, whats "positive" goes "negative" and whats "negative" goes "positive" with respect to y.
If a shape is a subset (made of
of quadrants
then the part
that lies in the second quadrant gets mapped to
and part
that lies in third quadrant gets mapped to
Hope this helps.
