There are four main blood groups (types of blood): A, B, AB and O. Your blood group is determined by the genes you inherit from your parents. Each group can be either RhD positive or RhD negative, which means your blood group can be one of the eight types shown below (see the Rh system).
Definition of polynomial : a mathematical expression of one or more algebraic terms each of which consists of a constant multiplied by one or more variables raised to a nonnegative integral power (such as a + bx + cx 2)
(For the general form of a polynomial, see Problem 6 below.) 6. The degree of a term is the sum of the exponents of all the variables in that term. In functions of a single variable, such as x, the degree of a term is simply the exponent. Example 2. The term 5x3 is of degree 3 in the variable x. Example 3.
