5.1: Roots and Radicals

Recall that a square root1 of a number is a number that when multiplied by itself yields the original number. For example, 5 is a square root of 25, because 52 = 25. Since ( − 5)2 = 25, we can say that − 5 is a square root of 25 as well. Every positive real number has two square roots, one positive and one negative.
