tolong jwb yaa dgn caraaa

x²+x > 0
x(x+1)> 0
x= 0
x = -1

x < -1 dan x > 0

²Log (x²+x) < ²Log 2
          x²+x < 2
       x²+x-2 < 0
     (x+2)(x-1) = 0
     x = -2 dan x = 1

-2 < x < 1

hp { -2 < x < -1 atau  0 < x < 1}

Batas x² + x > 0
x ( x + 1) > 0
x > 0 atau x < -1

²log(x² + x) < 1
log(x² + x) / log 2 < 1
log(x² + x) < log 2
x² + x < 2
x² + x - 2 < 0
(x + 2)(x - 1) < 0
 -2< x < 1


HP: -2 < x < -1 atau 0 < x < 1
