There are four main blood groups defined by the ABO system: 1  blood group A has A antigens on the red blood cells with anti-B antibodies in the plasma. 2  blood group B has B antigens with anti-A antibodies in the plasma. 3  blood group O has no antigens, but both anti-A and anti-B antibodies in the plasma.
A polynomial is a mathematical expression consisting of a sum of terms, each term including a variable or variables raised to a power and multiplied by a coefficient. A polynomial is a mathematical expression consisting of a sum of terms, each term including a variable or variables raised to a power and multiplied by a coefficient. The simplest polynomials have one variable. A one-variable (univariate) polynomial of degree n has the following form: anxn + an-1xn-1 + ...
A polynomial P(v) with all terms having degree n is homogeneous as P(Av) = AnP(v) for all vectors v and scalars A. A differential equation of the form dy/dx = M(x,y) / N(x,y) is homogeneous if M and N are homogeneous of the same degree. Proof: Let M and N be both homogeneous polynomials of degree K.
