Question 198828: Write three quadratic equations, with a, b, and c (coefficients of x2, x, and the constant) as:
Integers
Rational numbers
Irrational numbers
I don't understand how to set these up... can someone give me some examples and explanations so i can form my own equations?

1. Integers: any whole number
Let a=2, b=6, c=-12 (which are all whole numbers)

2. Rational Number: any number that is a ratio (or fraction) of two integers. So and are rational numbers
Let ,, (which are all fractions of whole numbers)

3. Irrational number: any number that cannot be represented by a fraction of two integers. For example and are irrational numbers
