Add the following rational expressions and make sure you answer is simplified:
\n" ); document.write( "\"%28x%5E3-x%5E2-10x%29%2F%28x%5E2-8x%2B16%29\" + \"%28-3x%5E2-6x%2B64%29%2F%28x%5E2-8x%2B16%29\" =
\n" ); document.write( ":
\n" ); document.write( "They have the same denominators so write it:
\n" ); document.write( "\"%28%28x%5E3-x%5E2-10x%29+%2B+%28-3x%5E2-6x%2B64%29%29%2F%28x%5E2-8x%2B16%29\"
\n" ); document.write( ":
\n" ); document.write( "\"%28x%5E3-x%5E2-10x+-+3x%5E2-6x%2B64%29%2F%28%28x-4%29%28x-4%29%29\": remove brackets, factor denominator as you did
\n" ); document.write( ":
\n" ); document.write( "\"%28x%5E3+-+x%5E2+-+3x%5E2+-+10x+-+6x+%2B+64%29%2F%28%28x-4%29%28x-4%29%29\"; group like terms
\n" ); document.write( ":
\n" ); document.write( "\"%28x%5E3-4x%5E2-16x%2B64%29%2F%28%28x-4%29%28x-4%29%29\"; combined like terms
\n" ); document.write( ":
\n" ); document.write( "\"%28x%5E2%28x-4%29-16%28x-4%29%29%2F%28%28x-4%29%28x-4%29%29\"; group and factor
\n" ); document.write( ":
\n" ); document.write( "\"%28%28x-4%29%28x%5E2-16%29%29%2F%28%28x-4%29%28x-4%29%29\"; factor out (x-4)
\n" ); document.write( ":
\n" ); document.write( "\"%28%28x-4%29%28x-4%29%28x%2B4%29%29%2F%28%28x-4%29%28x-4%29%29\": (x^2-16) can be factored (difference of squares)
\n" ); document.write( ":
\n" ); document.write( "Cancel out both (x-4)'s and you have:
\n" ); document.write( "x + 4 \r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
\n" );
