You can put this solution on YOUR website!
\"sum or difference of two squares\", from a trinomial? Not likely.\r

\n" ); document.write( "\n" ); document.write( " $\"%281%2F4%29%28x%5E2%2B16x%2B36%29\"$ , assuming your \"1/4\" is a factor for the x^2 term only. (You showed no other grouping symbols.)\r

\n" ); document.write( "\n" ); document.write( "Square term to Complete the Square is $\"%2816%2F2%29%5E2=64\"$ .
\n" ); document.write( " $\"%28x%5E2%2B16x%2B64-64%2B36%29\"$
\n" ); document.write( " $\"%28x%2B8%29%5E2-28\"$
\n" ); document.write( "The best you can do for what you ask is $\"%28%28x%2B8%29-sqrt%2828%29%29%28%28x%2B8%29%2Bsqrt%2828%29%29\"$ to represent your difference of two squares. Maybe this means that what you wanted were $\"%28x%2B8%29%5E2-%28sqrt%2828%29%29%5E2\"$ . \n" ); document.write( "
