We learned this in class, but I haven't yet grasped the concept. The sheet says \"Solve the equation. Identify any double roots.\" The problem is
\n" ); document.write( "x^2+2=11.
\n" ); document.write( "I believe you're supposed to equal it to zero. So far, I have:
\n" ); document.write( "x^2-9=0
\n" ); document.write( "Then, I added zero to the other side.
\n" ); document.write( "X^2=9
\n" ); document.write( "I managed to get x=3, but I'm not positive that it's right, and I don't know what a \"double root\" is. Is this a double root?
\n" ); document.write( "===============
\n" ); document.write( "x^2 = 9
\n" ); document.write( "x = 3
\n" ); document.write( "x = -3
\n" ); document.write( "----------
\n" ); document.write( "Not a double root, 2 separate roots.
\n" ); document.write( "==================
\n" ); document.write( "x^2 - 2x + 1 = 0
\n" ); document.write( "(x-1)^2 = 0
\n" ); document.write( "x = 1
\n" ); document.write( "x = 1
\n" ); document.write( "--------------
\n" ); document.write( "2 solutions, both +1.
\n" ); document.write( "That's a double root. \n" ); document.write( "
\n" );
