\"x-sqrt%282x%29-4=2\"\r
\n" ); document.write( "\n" ); document.write( "Let's get the square root on one side and everything else on another to get:
\n" ); document.write( "\"x-sqrt%282x%29-4%2Bsqrt%282x%29-2=2%2Bsqrt%282x%29-2\"
\n" ); document.write( "\"x-6=sqrt%282x%29\"\r
\n" ); document.write( "\n" ); document.write( "Now to get rid of the square root, we do the opposite of square root which is square both sides to get:
\n" ); document.write( "\"%28x-6%29%5E2=%28sqrt%282x%29%29%5E2\"
\n" ); document.write( "\"%28x-6%29%5E2=2x\"
\n" ); document.write( "\"%28x-6%29%28x-6%29=2x\"\r
\n" ); document.write( "\n" ); document.write( "Using the foil rule we get:
\n" ); document.write( "\"x%5E2-12x%2B36=2x\"
\n" ); document.write( "\"x%5E2-12x%2B36-2x=2x-2x\"
\n" ); document.write( "\"x%5E2-14x%2B36=0\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "I will let you try the rest from here... this is just a quadratic-- we know how to solve for x in this case (((HINT: you have a special RULEs for QUADRATICS)))\r
\n" ); document.write( "\n" ); document.write( "Let me know if you are still unsure where to go from here! Good luck!
