Algebra.Com's Answer #12548 by stanbon(75887)![]() ![]() ![]() 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 \n" ); document.write( "\n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
