Ba thuật toán giải phương trình, bất phương trình, hệ phương trình vô tỷ bằng cách thêm bớt biểu thức liên hợp

Abstract

Equation, inequation and equation systems containing roots are those mathematical problems grading students in university entrance exams. Subtracting and adding integrated expressions are typical in these problems. This article proposes three algorithms to solve irrational equations, inequations and equation systems by adding and substracting integrated expressions of “Bezout value”, “original secant”, “numerator similarity”.
