跪求f(x)=(2mx-m^2 1)/(x^2 1)(x∈R）0 (BC CA AB)/2跪求f(x)=(2mx-m^2 1)/(x^2 1)(x∈R）0 (BC CA AB)/2

题目

跪求f(x)=(2mx-m^2 1)/(x^2 1)(x∈R）0 (BC CA AB)/2跪求f(x)=(2mx-m^2 1)/(x^2 1)(x∈R）0 (BC CA AB)/2
(60*140 50*140)*2 60*500

答案

a>0,f(x)=loga(x^2-ax)在(-1/2,0)上单调递增因为x=3*3*3*(-5)=-135因为10^-6.5*10^4.5-10^-6.5 = -3.1622776601684 * 10 -7AD BE CF=(AB BC CA) (BC/2 CA/2 AB/2)
