Algebra II Help (Medal) Equation below:
2/(4+ square root 6) - 2/(4-square root 6)
please, you have to razionalize both your terms. For example, I multiply both numerator and denominator of your first term, by 4-sqrt(6): namely: \[\frac{ 2 }{ 4+\sqrt{6} }=\frac{ 2(4-\sqrt{6}) }{ (4+\sqrt{6})(4-\sqrt{6}) }=\]
\[=\frac{ 2(4-\sqrt{6}) }{ 16-6 }=\frac{ 2(4-\sqrt{6}) }{ 10 }=\frac{ 4-\sqrt{6} }{ 5 }\]
Now, please do the same with your second term, namely multiply both numerator and denominator, by 4+sqrt(6) @haleholmes
\[\frac{ 8+\sqrt{12} }{ 16-6 }\]
I got: \[\frac{ 8+2\sqrt{6} }{ 10 }\]
I was going to post the more simplified one but my computer was being mean. Alright, now I subtract right?
yes!
one sec
please, keep in mind that your second term is, after simplification: \[\frac{ 4+\sqrt{6} }{ 5 }\]
\[4 + \sqrt{6}\]
please note that you have to do this calculus: \[\frac{ 4-\sqrt{6} }{ 5 }-\frac{ 4+\sqrt{6} }{ 5 }=...\]
I have no idea
what is the problem?
The calculus. What do I do with that?
common least multiple is 5, so we have: \[\frac{ (4-\sqrt{6})-(4+\sqrt{6}) }{ 5 }=\frac{ 4-\sqrt{6}-4+\sqrt{6} }{ 5 }=...\]
please, what is the result?
It looks like the top just cancels out
oops I have made an error...
\[\frac{ (4-\sqrt{6})-(4+\sqrt{6} )}{ 5 }=\frac{ 4-\sqrt{6}-4-\sqrt{6} }{ 5 }=...\]
please, what is the result?
Its being annoying one more sec
