www.stat.pitt.edu1.5 Quadratic forms in normal random vectors Let X˘N p( ;). A quadratic form in Xis a random variable of the form Y = X0AX= Xp i=1 Xp j=1 X ia ijX j; where A is a p psymmetric matrix and X i is the ith element of X. We are interested in the distribution of quadratic forms and the conditions under which two quadratic forms are independent ...

R has the form f(x) = a ¢ x2.Generalization of this notion to two variables is the quadratic form Q(x1;x2) = a11x 2 1 +a12x1x2 +a21x2x1 +a22x 2 2: Here each term has degree 2 (the sum of exponents is 2 for all summands).

www.mcckc.eduSOLVING QUADRATIC EQUATIONS A quadratic equation in is an equation that may be written in the standard quadratic form if . There are four different methods used to solve equations of this type. Factoring Method If the quadratic polynomial can be factored, the Zero Product Property may be used.
