Algebra.Com's Answer #360620 by rapaljer(4671)![]() ![]() You can put this solution on YOUR website! You must first find the largest perfect square that is a factor of 120 in the square root sign. This would be 4, so break down the 120=4*30\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "I have a REALLY good explanation of square roots on my website. You can find my website by use of the easy-to-remember and easy-to-spell link www.mathinlivingcolor.com. At the bottom of this page is a link that will take you to my FREE Homepage. Look near the top of this page for the link \"Basic, Intermediate, and College Algebra: One Step at a Time\", click on \"Basic Algebra\" and look in Chapter 5 for the section \"5.01 Square Roots.\" I also have a FREE video of me teaching this topic (from my younger days before I retired!) Look on my Homepage for the link \"Rapalje Videos in Living Color\" and look in Basic Algebra for the one on Square Roots. My explanations should be a LOT easier to understand than the traditional textbooks you are probably using.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Happy New Year!!
