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 principal … WebRoots of Polynomials The formula is used to assess the roots of two-degree quadratic equations, such as ax2 + bx + c = 0 x= −b±√b2−4ac 2a x = − b ± b 2 − 4 a c 2 a Higher degree polynomial formulas are a little more difficult.
