a man is 37 years old and his child is 8 years old.
\n" ); document.write( "How many years ago was the product of their ages 96?
\n" ); document.write( ":
\n" ); document.write( "Let y = no. of yrs ago that this was true
\n" ); document.write( ":
\n" ); document.write( "(37-y)(8-y) = 96
\n" ); document.write( "FOIL
\n" ); document.write( "296 - 37y - 8y + y^2 = 96
\n" ); document.write( ":
\n" ); document.write( "y^2 - 45y + 296 - 96 = 0
\n" ); document.write( "y^2 - 45y + 200 = 0
\n" ); document.write( "Factors to
\n" ); document.write( "(y-5)(y-40) = 0
\n" ); document.write( "Two solutions
\n" ); document.write( "y = 40
\n" ); document.write( "and
\n" ); document.write( "y = 5 yrs, is the only reasonable answer
\n" ); document.write( ":
\n" ); document.write( "5 yrs ago: 32 * 3 = 96
