You can put this solution on YOUR website!
When you have the sum of two expressions, \"a\" and \"b\",
\n" ); document.write( "and want to calculate the square of that sum you can use the formula for \"square of a binomial\":
\n" ); document.write( "\"%28a%2Bb%29%5E2=a%5E2%2B2%2Aa%2Ab%2Bb%5E2\"
\n" ); document.write( "Applying that to the problem we get
\n" ); document.write( "
\n" ); document.write( "We keep calculating indicated operations and simplifying.
\n" ); document.write( "=\"%283sqrt%28x%29%29%5E2%2B12sqrt%28x%29%2B4\"
\n" ); document.write( "=\"3%5E2%2A%28sqrt%28x%29%29%5E2%2B12sqrt%28x%29%2B4\"
\n" ); document.write( "=\"9x%2B12sqrt%28x%29%2B4\"
\n" ); document.write( "
