\n" ); document.write( "Let x = no. yrs ago for this to be true
\n" ); document.write( ":
\n" ); document.write( "(37-x)(8-x) = 96
\n" ); document.write( "FOIL
\n" ); document.write( "296 - 37x - 8x + x^2 = 96
\n" ); document.write( "x^2 - 45x + 296 - 96 = 0
\n" ); document.write( "x^2 - 45x + 200 = 0
\n" ); document.write( "Factors to
\n" ); document.write( "(x-40)(x-5) = 0
\n" ); document.write( "x = 5 yrs is the only reasonable solution
\n" ); document.write( ":
