Algebra.Com's Answer #12548 by stanbon(75887)\"\" \"About 
You can put this solution on YOUR website!
Because it is a difference of two squares
\n" ); document.write( "you could factor it as [(a+b)^2+(a-b)^2][(a+b)^2-(a-b)^2]
\n" ); document.write( "I'm going to called this [1st part][2nd part].
\n" ); document.write( "You can factor the 2nd part because it is the difference
\n" ); document.write( "of two squares to get:
\n" ); document.write( "[(a+b)+(a-b)][(a+b)-(a-b)]
\n" ); document.write( "= [2a][2b]
\n" ); document.write( "Now, what about that 1st part?!!
\n" ); document.write( "If you expand it you get the following:
\n" ); document.write( " (a^2+2ab+b^2)+(a^2-2ab+b^2)
\n" ); document.write( "Adding you get 2a^2 + 2b^2
\n" ); document.write( "So, putting the pieces together you have:
\n" ); document.write( "[2a^2+2b^2][2a}{2b]
\n" ); document.write( "I'll let you figure out what you want to
\n" ); document.write( "do with that. It can be simplified in
\n" ); document.write( "several ways but not significantly.\r
