Algebra.Com's Answer #365841 by ad_alta(240)![]() ![]() You can put this solution on YOUR website! This is really quite messy, so I can't type out all the work. r=[(s+1) {+/-} sqrt(s^2+2s+4aL+1)]/2L.\r \n" ); document.write( "\n" ); document.write( "The {+/-} indicates plus or minus. I suggest you work backward from this to wherever you were stuck. Good luck! \n" ); document.write( " |
