1.\"%281%2B+2%2Fx%2B+4%2Fx2%2B+8%2Fx3%29%2F%281-+16%2Fx4%29\"
\n" ); document.write( "Multiply top and bottom by \"x%5E4\"
\n" ); document.write( "\"%28x%5E4%2B+2x%5E3%2B+4x%5E2%2B+8x%29%2F%28x%5E4-16%29\"
\n" ); document.write( "\"x%28x%5E3%2B+2x%5E2%2B+4x%2B+8%29%2F%28x%5E4-16%29\"
\n" ); document.write( "Let's look at the denominator first.
\n" ); document.write( "\"%28x%5E4-16%29=%28x%5E2%2B4%29%28x%5E2-4%29\"
\n" ); document.write( "\"%28x%5E4-16%29=%28x%5E2%2B4%29%28x%2B2%29%28x-2%29\"
\n" ); document.write( "Now the numerator
\n" ); document.write( "\"x%28x%5E3%2B2x%5E2%2B4x%2B8%29%29=x%28x%5E2%2B4%29%28x%2B2%29\"
\n" ); document.write( "Let's substitute
\n" ); document.write( "\"x%28x%5E3%2B+2x%5E2%2B+4x%2B+8%29%2F%28x%5E4-16%29\"
\n" ); document.write( "
\n" ); document.write( "\"x%2F%28x-2%29\"
\n" ); document.write( "Good idea to check the answer
\n" ); document.write( "Let's try x=3
\n" ); document.write( "Equation 1 gives an answer
\n" ); document.write( "1.Numerator=\"%281%2B+2%2F3%2B+4%2F9%2B+8%2F27%29\"
\n" ); document.write( "1.Denominator=\"%281-+16%2F81%29\"
\n" ); document.write( "Numerator = 2.470407
\n" ); document.write( "Denominator = 0.802469
\n" ); document.write( "Numerator/Denominator = 3
\n" ); document.write( "\"x%2F%28x-2%29=3%2F%283-2%29\"
\n" ); document.write( "\"x%2F%28x-2%29=3\"
\n" ); document.write( "3=3
\n" ); document.write( "Good answer.
\n" ); document.write( "\"%281%2B+2%2Fx%2B+4%2Fx2%2B+8%2Fx3%29%2F%281-+16%2Fx4%29=x%2F%28x-2%29\"
