You can put this solution on YOUR website!
Factor Completely: a(to the power of 4) -(minus) b(to the power of 4)
\n" ); document.write( ":
\n" ); document.write( "We can write it:
\n" ); document.write( "(a^4 - b^4)
\n" ); document.write( ":
\n" ); document.write( "Recognize this as the \"difference of squares\"; factors to:
\n" ); document.write( "(a^2 + b^2) (a^2 - b^2)
\n" ); document.write( ":
\n" ); document.write( "(a^2 - b^2) is also the difference of squares and factors to:
\n" ); document.write( "(a + b)(a - b)
\n" ); document.write( ":
\n" ); document.write( "So you have (a^2 + b^2)(a - b)(a + b)
\n" ); document.write( "
\n" );
