If you subtract a number from its square, the result is 12. Find all such numbers
\n" ); document.write( ":
\n" ); document.write( "x^2 - x = 12
\n" ); document.write( ";
\n" ); document.write( "x^2 - x - 12 = 0
\n" ); document.write( "factor
\n" ); document.write( "(x-4)(x+3) = 0
\n" ); document.write( "Two solutions
\n" ); document.write( "x = +4
\n" ); document.write( "and
\n" ); document.write( "x = -3
\n" ); document.write( ":
\n" ); document.write( "Check the 2nd solution
\n" ); document.write( "(-3)^2 - (-3) = 12
\n" ); document.write( "9 + 3 = 12 \n" ); document.write( "
\n" );
