First step get a common denominator for each side (which will be the
product of the two binomials)

Second step, now that each side is a single fraction, cross multiply
the two fractions (numerator times other side denominator & vice
versa.

Last simplify the fractions.



After following my step 1 you get this equation (note "/" is a fraction bar)

(2x+7)/(x^2+7x+12) = (2x+7)/(x^2+7x+10)

After you cross multiply you get: (note there are no fractions)
2x^3+14x^2+20x+7x^2+49x +70 = 2x^3+14x^2+24x+7x^2+49x+84

After subtracting common values from both sides you get
20x+70 = 24x+84

-14 = 4x, so x=-3.5

Well, well, well, despite people having very big mouths here. so far none is come forward to solve the equation.

tells us something, doesn't it?

And no, coming again with a totally another equation is of course not a solution.
That will be a very very dumb reaction , and is always done by someone who feels extremely threatened by this very good, practical and elegant system.

We'll see who is so dumb to come with another equation, so we can have a laugh, again!

Oh and btw Pi=3.14159265359 is factually wrong!
