1/(x+y)=(x-y)/(x²-y²1/(x-y)=(x+y)/(x²-y²======以下答案可供参考======供参考答案1:x×y啦,因为x×y的答案才是最准确的啦供参考答案2:(X²-Y²)分之(X-Y)和(X²-Y²)分之(X+Y)供参考答案3:你好1/(x+y)+1/(x-y)=(x-y)/(x+y)(x-y)+(x+y)/(x-y)(x+y)=[(x-y)+(x+y)]/(x+y)(x-y)=2x/(x²-y²)【数学辅导团】为您解答,不理解请追问,理解请及时选为满意回答!(*^__^*)谢谢!供参考答案4:∵最简公分母为(x+y)(x-y) ∴x+y/1=(x+y)(x-y)/1×(x-y)=(x+y)(x-y)/x-y (记住不要化简) ∴x-y/1=(x+y)(x-y)/1×(x+y)=(x-y)(x+y)/x-y (“/”是分十一)
