不等式问题一直是高考命题较为稳定的一个热点,对有些不等式的求解,常有同学因不会变通或思维定势,导致因运算过繁而计算终止或弃而不解,甚为可惜.针对这种情况,本文谈谈不等式问题的优化策略.1逆向思考,执果索因例1已知适合不等式｜x2-4x+p｜+｜x-3｜≤5的x的最大值为3,求p的?
The inequality problem has always been a hot spot for the college entrance examination proposition to be stable. To solve some inequalities, it is often a pity that students will not be able to adapt or think in a fixed position because of computational delays or discards due to over-computation. In this case, this article talks about the optimization strategy of inequality problems. 1 The reverse thinking, the results of the implementation of fruit factor 1 is known to fit the inequality |x2-4x+p|+|x-3|≤5. The maximum value of x is 3. p’s?
