## anonymous one year ago One category that is important to understand is rational numbers. A rational number is a number that can be expressed as an integer divided by another integer. In this unit you will encounter rational expressions, which are a form of polynomial. Knowing what the definition of rational numbers is, what form do you expect rational expressions to take? @zepdrix

Hey boo :) If we have integers $$\large\rm \color{orangered}{a}$$ and $$\large\rm \color{royalblue}{b}$$, a rational number would look like the quotient of these integers: $$\large\rm \dfrac{\color{orangered}{a}}{\color{royalblue}{b}}$$.

If instead we have polynomials, examples: $$\large\rm \color{orangered}{x^2+2x+3}$$ and $$\large\rm \color{royalblue}{x^3+7x-2}$$ What do you think a rational expression might look like? Try to follow the colors I used.

Just to clarify: rational number is the ratio of integers. rational expression is the ratio of polynomials.
