WebYou ask a good question and you are right in your thinking. By definition, the Principal root of a number is the same sign as the real number. For example, both -4 and +4 are the square roots of 16. So, to talk about just the principal root of 16 means we discuss the "n"th root of 16 that has the "same sign" as the number in question. Since 16 is positive, the … WebA polynomial equation whose degree is 2, is known as quadratic equation.
