How many unique roots will a fourth degree polynomial function have?

A fourth degree polynomial function can have up to four unique roots. However, the actual number of unique roots can be fewer, depending on the polynomial's coefficients and the nature of its roots. Roots can be real or complex, and some roots may be repeated (multiplicity). Thus, the number of unique roots can range from zero to four.

How many square roots can a positive number have?

Every positive number has two square roots, though the roots are not always whole numbers (or even rational numbers). The more obvious of each numbers roots is the positive one.The positive square root of 4 is 2, because 2*2=4.The positive square root of 5 is roughly 2.236068.The other square root of a number is the negative inverse of their positive root. This is because when two negative numbers are multiplied together the negative signs "cancel out", leaving a positive number.The negative square root of 4 is -2, because -2*-2=4.The negative square root of 5 is roughly -2.236068.Zero has only one square root, itself, and no negative number has any (real number) square roots, since no number multiplied by itself will result in a negative.
