I am thinking of three consecutive numbers. If I multiply the first with the second and then subtract three times the third, the result is 57. What are the numbers?
\n" ); document.write( "-------------------------
\n" ); document.write( "1st: x-1
\n" ); document.write( "2nd: x
\n" ); document.write( "3rd: x+1
\n" ); document.write( "------------------
\n" ); document.write( "Equation:
\n" ); document.write( "(x-1)x-3(x+1)= 57
\n" ); document.write( "x^2-x-3x-3 = 57
\n" ); document.write( "x^2-4x-60 = 0
\n" ); document.write( "x^2-10x+6x-60 = 0
\n" ); document.write( "x(x-10)+6(x-10) = 0
\n" ); document.write( "(x-10)(x+6) = 0
\n" ); document.write( "x = 10 or x = -6
\n" ); document.write( "--------------------------------
\n" ); document.write( "If x = 10 the numbers are 9,10,11
\n" ); document.write( "-----------
\n" ); document.write( "If x = -6 the numbers are -7,-6,-5
