Question

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?

Answer 1

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: \(\large\rm \dfrac{\color{orangered}{a}}{\color{royalblue}{b}}\).

Answer 2

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.

Answer 3

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