Multiply each term in the first group by each term in the second group using FOIL method
\n" ); document.write( "(x * x + x * 8 - 8 * x - 8 * 8)
\n" ); document.write( "Multiply x by x to get x^2
\n" ); document.write( "(x^2 + x * 8 - 8 * x - 8 * 8)
\n" ); document.write( "Multiply x by 8 to get 8x
\n" ); document.write( "(x^2 + 8x -8 * x -8 * 8)
\n" ); document.write( "Multiply-8 by x to get -8x
\n" ); document.write( "(X^2 + 8x -8x -8 *8)
\n" ); document.write( "Multiply -8 by 8 to get -64
\n" ); document.write( "(x^2 + 8x -8x -64)
\n" ); document.write( "x is a factor of both 8x and -8x
\n" ); document.write( "(x^2 +(8-8)x -64)
\n" ); document.write( "To add integers with different signs, subtract their absolute values and give the result the same sign as the integer with the greater absolute value.
\n" ); document.write( "(x^2 + (0)x -64)
\n" ); document.write( "remove parentheses
\n" ); document.write( "(x^2 -64)
\n" ); document.write( "Therefore the answer is (x^2 -64) \n" ); document.write( "

\n" );
