The sum of the ages of a mother and her daughter are 44,3 years ago the product of their age was 192. How old is d daughter now?
\n" ); document.write( "Let d = daughter's age
\n" ); document.write( "and m = mom's age
\n" ); document.write( ".
\n" ); document.write( "from:\"The sum of the ages of a mother and her daughter are 44\"
\n" ); document.write( "d+m = 44
\n" ); document.write( "so,
\n" ); document.write( "m = 44-d
\n" ); document.write( ".
\n" ); document.write( "from:\"3 years ago the product of their age was 192. How old is d daughter now?\"
\n" ); document.write( "(d-3)(m-3) = 192
\n" ); document.write( "(d-3)(44-d-3) = 192
\n" ); document.write( "(d-3)(-d+41) = 192
\n" ); document.write( "-d^2+41d+3d-123 = 192
\n" ); document.write( "-d^2+44d-123 = 192
\n" ); document.write( "-d^2+44d-315 = 0
\n" ); document.write( "d^2-44d+315 = 0
\n" ); document.write( "d^2-9d-35d+315 = 0
\n" ); document.write( "(d^2-9d)-(35d-315) = 0
\n" ); document.write( "d(d-9)-35(d-9) = 0
\n" ); document.write( "(d-9)(d-35) = 0
\n" ); document.write( "d = {9,35}
\n" ); document.write( "The daughter is 9 years old \n" ); document.write( "
\n" );
