Can you help me multiply this quadratic equation?
\n" ); document.write( "121-x^2/x^2-22x+120 times x^2-24x+140/x^2-18x+77
\n" ); document.write( "I would set up the 1st equation like this:
\n" ); document.write( "Numerator:: 121-x^2/x^2-22x+120 =(11+x)(11-x)/(x-12)(x-10)
\n" ); document.write( "and
\n" ); document.write( "Denominator:(x^2-24x+140)/(x^2-18x+77) = (x-10)(x-14)/(x-11)(x-7)
\n" ); document.write( "-------------
\n" ); document.write( "Multiply to get:
\n" ); document.write( "[(11+x)(11-x)/(x-12)(x-10)]
\n" ); document.write( "Cancel factors common to numerator and denominator to get:
\n" ); document.write( "[11+x))/(x-12)]
\n" ); document.write( "After I did the equations but my answer differed from the answer key.
\n" ); document.write( "My answer is:
\n" ); document.write( "-(x+11)(x-14)/(x-12)(x-7)
\n" ); document.write( "----------
