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!

Answer:
sqrt(2)
sqrt(3)
6 - sqrt(2) sqrt(3)
Step-by-step explanation:
sqrt(2) is an irrational number.
sqrt(3) is an irrational number.
Let x = 6 - sqrt(2) - sqrt(3).
x is also an irrational number.
Now add the three numbers above:
sqrt(2) + sqrt(3) + [6 - sqrt(2) - sqrt(3)] =
= sqrt(2) + sqrt(3) + 6 - sqrt(2) - sqrt(3)
= 6
