Rene' Descartes is credited with founding rational root theorem. He also created the rules of signs to be used with solving equations.
When a rational numbers is divided by an irrational number, the answer is irrational for every non-zero rational number.
Well, honey, the square root of zero is actually just zero. And guess what? Zero is as rational as it gets in the number world. So, yes, the square root of zero is a rational number. But hey, don't sweat it if math isn't your thing, we can't all be numbers wizards.
Undefined: You cannot divide by zero
Rational expressions are fractions and are therefore undefined if the denominator is zero; the domain of a rational function is all real numbers except those that make the denominator of the related rational expression equal to 0. If a denominator contains variables, set it equal to zero and solve.

In algebra, the rational root theorem (or rational root test, rational zero theorem or rational zero test) states a constraint on rational solutions (or roots) of a polynomialequationwith integer coefficients.If a0 and an are nonzero, then each rational solution x, when written as a fraction x = p/q in lowest terms (i.e., the greatest common divisor of p and q is 1), satisfiesp is an integer factor of the constant term a0, andq is an integer factor of the leading coefficient an.The rational root theorem is a special case (for a single linear factor) of Gauss's lemmaon the factorization of polynomials. The integral root theorem is a special case of the rational root theorem if the leading coefficient an = 1.

Zero Theorem - 2010 SUSPENDED was released on: USA: 2010
Zero is a rational number and an integer.

0=0
A rational number can be expressed as a fraction or ratio of two integers. Zero is an integer. Therefore, zero is a rational number EXCEPT, that the denominator of a rational number cannot be zero. You can't divide by zero.
