Answer:
1) ( 6+[tex]\sqrt{6}[/tex] ) / 2 2) 2 [tex]\sqrt{3}[/tex] - 3
Step-by-step explanation:
I got the same thing as the other person, but typing it out would take forever just to give you the same result.
You do use a technique called rationalizing a denominator to eliminate the radical. The point of rationalizing a denominator is to make it easier to understand what the quantity really is by removing radicals from the denominators.
1) ( 6+[tex]\sqrt{6}[/tex] ) / 2
2) I got the same answer but I put in 1 more step. It looks like the person caught it though.
From the -3 + [tex]\sqrt{12}[/tex]
-3 + [tex]\sqrt{4} \sqrt{3}[/tex]
-3 + 2 [tex]\sqrt{3}[/tex] Rearrange
2 [tex]\sqrt{3}[/tex] - 3
