Algebra.Com's Answer #48957 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! convert (x^2+y^2+2x-10=0) into (x-h)^2+(y-k)^2=r^2 format \n" ); document.write( "--------- \n" ); document.write( "You need to \"complete the square\" on the x terms and separately \n" ); document.write( "on the y terms, as follows:\r \n" ); document.write( "\n" ); document.write( "--------------- \n" ); document.write( "(x^2+2x+1) + (y^2) = 10+1 \n" ); document.write( "(x+1)^2 + (y-0)^2 = [sqrt(11)]^2 \n" ); document.write( "Center is at (-1,0) \n" ); document.write( "Radius is sqrt(11) \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
