http://www.icoachmath.com/math_dictionary/Rational_Equation.html A rational equation is one involving a ratio of expressions, that is, one expression (such as a polynomial) divided by another. In a quick Web search for the phrase "irrational equation", the only mathematical references I found were in lists of topics covered in high school algebra courses. Thus it appears that this is a pedagogical term only, not one that mathematicians use in the "real world" (after graduation). The closest I could see to a definition is something like "an equation involving radicals". I would not use the term "irrational equation" for this; I'd just say "radical equation".

Well, it seems rational equations contain fractional terms and irrational contain square roots...

An irrational equation is "an equation having an unknown raised to some fractional power. Also known as radical equation. " Read more: http://www.answers.com/topic/irrational-equation#ixzz1x6c8g5MS
