Find the product. (4m+2n)^2
\n" ); document.write( "= (4m+2n)*(4m+2n)
\n" ); document.write( "= 4m*(4m+2n) + 2n(4m+2n)
\n" ); document.write( "= \"16m%5E2+%2B+8mn+%2B+8mn+%2B+4n%5E2\"
\n" ); document.write( "= \"16m%5E2+%2B+16mn+%2B+4n%5E2\"
\n" ); document.write( "--------------------------
\n" ); document.write( "\"%28a%2Bb%29%5E2+=+a%5E2+%2B+2ab+%2B+b%5E2\"
\n" ); document.write( "a = 4m, b = 2n
\n" ); document.write( "
