跪求u=u2(x) u2(y) u2(z)a(a2-2ab-b2)-b(2a2 ab-b2)∴2ab/a b≤2ab/2√ab=√ab |x-1| |x-2|>0

跪求u=u2(x)u2(y)u2(z)a(a2-2ab-b2)-b(2a2ab-b2)∴2ab/ab≤2ab/2√ab=√ab|x-1||x-2|>0跪求u=u2(x)u2(y)u2(z)a(a2-2

跪求u=u2(x) u2(y) u2(z)a(a2-2ab-b2)-b(2a2 ab-b2)∴2ab/a b≤2ab/2√ab=√ab |x-1| |x-2|>0
跪求u=u2(x) u2(y) u2(z)a(a2-2ab-b2)-b(2a2 ab-b2)
∴2ab/a b≤2ab/2√ab=√ab |x-1| |x-2|>0

跪求u=u2(x) u2(y) u2(z)a(a2-2ab-b2)-b(2a2 ab-b2)∴2ab/a b≤2ab/2√ab=√ab |x-1| |x-2|>0
y=x^3 x-2∴2ab/a b≤2ab/2√ab=√ab 比较|x-1| |x-2|>0比较y=x^3 x-2
