D. Each of the equations has an infinite number of solutions that are not common to the other. 相关知识点: 试题来源: 解析B Choice (A) is true. The point of intersection is a solution to each of the equations because it lies on each equation. Every point on a line is a solution to...
Looking at the answer choices should make it clear that this equation cannot be solved by factoring. So use the quadratic formula:x=(-2 ±√(4-(-44)))2=(-2 ±√(48))2=(-2 ± 4√3)2=-1 ± 2√3So the two solutions are -1+2√3 and -1-2√3....
解析 Solution: (E). The original equation can be rewritten as |x-2|+|x-3|=|(x-2)-(x-3)| By property (1), we have (x-2)(x-3)≤0 Solving we get:2≤x≤3 . Therefore, the equation has more than 3 solutions. 反馈 收藏 ...
