\"A year ago, a mother was eight as old as her daughter\" ___ m - 1 = 8(d - 1) ___ m = 8d - 7\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"her age is the square of her daughter's age\" ___ m = d^2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "substituting ___ (8d - 7) = d^2 ___ 0 = d^2 - 8d + 7\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "factoring ___ 0 = (d - 7)(d - 1)
\n" ); document.write( "
\n" );
