Algebra.Com's Answer #85535 by ankor@dixie-net.com(22740) You can put this solution on YOUR website! simplify and rationalize the denominator Radical X^2+11 = 2radical 3X \n" ); document.write( ": \n" ); document.write( "The way I see this problem is you don't have a denominator here, I see it as: \n" ); document.write( " \n" ); document.write( ": \n" ); document.write( "Square both sides and you have: \n" ); document.write( "x^2 + 11 = 4(3x) \n" ); document.write( ": \n" ); document.write( "x^2 + 11 = 12x \n" ); document.write( ": \n" ); document.write( "x^2 - 12x + 11 = 0 \n" ); document.write( ": \n" ); document.write( "Factors to: \n" ); document.write( "(x-11)(x-1) = 0 \n" ); document.write( ": \n" ); document.write( "x = +11, x = +1; and both solutions check out \n" ); document.write( " |
