Abstract

Abstract: In this paper we give out a sufficient and solution of quadratic function’s maximum with theory of quadratic form and give out the definition of the positive definite property of the following homogeneous polynomials of degree In two variables function, based on the definite of local maximum of two variables function.

Key words: positive , , definite , , property, quadratic , , function, two , , variable , , function, maximum, extremisni
