You can put this solution on YOUR website!
(a + b)^2 is not equal to a^2 + b^2.

\n" ); document.write( "Simply, in $\"%28a%2Bb%29%5E2\"$ means that you need to add the numerals (or variables)before raising them to the 2nd power.
\n" ); document.write( "In $\"%28a%5E2+%2B+b%5E2%29\"$ means that you need to raised the numerals or variables to the 2nd power then add them.
\n" ); document.write( "To prove, pick $\"a=1\"$ and $\"b=2\"$
\n" ); document.write( " $\"%28a%2Bb%29%5E2=%281%2B2%29%5E2=3%5E2=9\"$ is not equal to $\"a%5E2%2Bb%5E2=1%5E2%2B2%5E2=1%2B4=5\"$
