化简(√a+√b+√ab)^2-(√a+√b-√ab)^2化简(√a+√b+√ab)^2-(√a+√b-√ab)^2化简(√a+√b+√ab)^2-(√a+√b-√ab)^2=(a+b+2√ab+2a

化简(√a+√b+√ab)^2-(√a+√b-√ab)^2
化简(√a+√b+√ab)^2-(√a+√b-√ab)^2

化简(√a+√b+√ab)^2-(√a+√b-√ab)^2
=(a+b+2√ab+2a√b+2b√a+ab)-(a+b+2√ab-2a√b-2b√a+ab)
=a+b+2√ab+2+2b√a+ab-a-b-2√ab+2a√b+2b√a-ab
=4(a√b+b√a)

√ab)^2-(√a+√b-√ab)^2
