document.write( "Any advice on how to find this would be great! I tried to follow the instructions given by the book but it did not work out so well! It says to find the answer by completing the square. I tend to get lost in that process when you add the 8 to both sides. \n" );

Algebra.Com's Answer #38627 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! Put the following function: y=x^2-6x+8 in the form y=a(x-h)2+k \n" ); document.write( "---------------- \n" ); document.write( "Rewrite as: \n" ); document.write( "y-8+? = x^2-6x+? \n" ); document.write( "To complete the square you need (-6/2)^2=9 \n" ); document.write( "Put that in place of the ? to get: \n" ); document.write( "y-8+9=x^2-6x+9 \n" ); document.write( "Rewrite as: \n" ); document.write( "y+1 = (x-3)^2 \n" ); document.write( "Then: \n" ); document.write( "y=(x-3)^2-1 \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
