Homework Help: math

Posted by peter on Tuesday, October 26, 2010 at 7:19am.


How would I rationalize this

I think it would be -

Multiply both sides by 11-root5
then use the foil method on the denominator to give you 55-5root5/121+5root11-5root11-5
the 2 roots would cancel out giving you 55-5root5/12-5

so would the answer be 55-5root5/7

thanks in advance
