Hello,
\n" ); document.write( "Let's have x be the first even integer and x+2 be the next and x+4 be the next. OK, now we can set up an equation like this:
\n" ); document.write( "x(x+4)=9(x+2)-24 Rewritten it looks like:
\n" ); document.write( "x^2+4x=9x+18-24 Rewritten as:
\n" ); document.write( "x^2+4x=9x-6 Subtract 9x and add 6 to both sides to get:
\n" ); document.write( "x^2-5x+6=0 Factor this out to be:
\n" ); document.write( "(x-3)(x-2)=0 Solve x:
\n" ); document.write( "x=3 This obviously doesn't work since it not an even integer so the answer is:
\n" ); document.write( "x=2 From here you know the next two even integers.
