Using synthetic division, we can find one real root a and we can find the … WebLikewise, any integer can be expressed as the ratio of two integers, thus all integers are rational. However, numbers like √2 are irrational because it is impossible to express √2 as a ratio of two integers. The first irrational numbers students encounter are the square roots of numbers that are not perfect squares.
