Domain restrictions of a rational expression. The domain of a rational expression or equation is a collection of the values for the variable that will not result in an undefined mathematical operation such as division by zero. H - 10 0 h - 2 0. H2 - 12h 20 0 factor.

Homework has started to get on my nerves. Fxx f x x. Because of this rational expressions have domain restrictions domain restrictions or values that the variables may not be.

X2 x1 lashaestone lashaestone 10172017. As it could also be written. A rational expression is a fraction where both our numerator and our denominator are polynomials so basically what that means is we have a fraction and the only powers of xs we have are whole positive numbers okay so we have a polynomial over a polynomial and more importantly our denominator cannot be equal to 0 we cant have a fraction where were dividing by 0 so as long as our denominator is not equal to 0 we are fine.
