Irrational number 1 = 0, and this latter polynomial has no rational roots (the only candidates to check are ±1, and "x", being greater than 1, is neither of these), so "x" is an irrational algebraic number. Because the algebraic numbers form a subfield of the real numbers, many irrational real numbers can be constructed by combining transcendental and algebraic numbers. For example, 3 + 2, + and "e" are irrational (and even transcendental). The decimal expansion of an irrational number never repeats or terminates (the latter being equivalent to repeating zeroes), unlike any rational number. The same is true for binary,
