You can put this solution on YOUR website!
$\"x%5E3%2B8\"$
\n" ); document.write( ":
\n" ); document.write( "You should recognize that 8 = 2^3, therefore this is the \"sum of cubes\"
\n" ); document.write( ":
\n" ); document.write( "Somewhere in your algebra book there a section called something like
\n" ); document.write( "\"Special factoring formulas\"
\n" ); document.write( ":
\n" ); document.write( "The sum of cubes is given as: a^3 + b^3 = (a + b)(a^2 - ab + b^2)
\n" ); document.write( ":
\n" ); document.write( "In your problem a = x and b = 2
\n" ); document.write( ":
\n" ); document.write( "x^3 + 8 = (x + 2)(x^2 - 2x + 4)
\n" ); document.write( ":
\n" ); document.write( "It's a good idea to learn this section or at least know where to find them so you can recognize expression in this category \n" ); document.write( "
