解含参数的一元二次方程整数解的问题,关键是要熟练掌握一元二次方程解的概念、解法、根的判别式、根与系数的关系,以及整数、完全平方数的性质,缩小未知数的取值范围,利用不等式组的解集得出整数解,并能运用分类 The key to solving the integer solution of a one-membered quadratic equation with parameters is to master the concept of a quadratic solution, the solution, the root discriminant, the relationship between the root and the coefficient, and the nature of integers and complete squares. Range of values, using the solution set of inequalities to arrive at an integer solution and applying the classification
