Multiply
\n" ); document.write( "(5a - 3b)^2
\n" ); document.write( "Is this correct 25a^2 - 9b^2
\n" ); document.write( "Thanks\r
\n" ); document.write( "\n" ); document.write( "Almost, you may be thinking of the difference of two squares, that is:
\n" ); document.write( "(5a-3b)(5a+3b) = \"%2825a%5E2-15ab%2B15ab-9b%5E2%29\" = \"%2825a%5E2-9b%5E2%29\"
\n" ); document.write( ".
\n" ); document.write( "The difference in this problem is that the entire quantity is taken twice:
\n" ); document.write( "\"%28%285a-3b%29%5E2%29\" = (5a-3b)(5a-3b) [Use FOIL to solve]
\n" ); document.write( "\"%2825a%5E2+-15ab-15ab%2B9b%5E2%29\" [Simplify]
\n" ); document.write( "\"%2825a%5E2-30ab%2B9b%5E2%29\"
\n" ); document.write( " \n" ); document.write( "
