How did my computer simplify this?

OpenStudy (doc.brown):

\[\frac{12-\sqrt{204}}6\]became\[\frac{-1}3\sqrt{51}+2\]

OpenStudy (welshfella):

sqrt204 = sqrt 4 * sqrt51 = 2 sqrt51

OpenStudy (welshfella):

Now you can do some simplifying

OpenStudy (theopenstudyowl):

There are quite a few steps to this operation.....

OpenStudy (welshfella):

12 - 2sqrt51 ------------- 6 Next step is to divide top and bottom by 2

OpenStudy (welshfella):

Can. You do that?

OpenStudy (doc.brown):

\[\frac{12-\sqrt{204}}{6}\]\[\frac{12-\sqrt{4}\sqrt{51}}6\]\[\frac{12-2\sqrt{51}}6\cdot\frac22\]\[\frac{6-\sqrt{51}}{3}\]\[\frac63-\frac{\sqrt{51}}3\]\[=2-\frac{\sqrt{51}}3\] Thanks
