Are both x^2+16 and x^3+27 factorable? Why or why not (explain).
\n" ); document.write( "
Sum of squares(\"matrix%281%2C3%2C+x%5E2+%2B+16%2C+or%2C+%28x%29%5E2+%2B+%284%29%5E2%29\") CANNOT be factored with INTEGERS. 
\n" ); document.write( "\"x%5E3+%2B+27\" follows the SUM OF CUBES method of factoring, or \"matrix%281%2C3%2C+a%5E3+%2B+b%5E3%2C+%22=%22%2C+%28a+%2B+b%29%28a%5E2+-+ab+%2B+b%5E2%29%29\", to factor to: \"highlight_green%28%28x+%2B+3%29%28x%5E2+-+3x+%2B+9%29%29\" \n" ); document.write( "
\n" );
