Question

Solve the following equation:
12logx+3log2+x=logx(x+2)+2

Open in App
Solution

12logx+3log2+x=logx(x+2)+2log[(x+2)x(x+2)]=log[100x(x+2)](x+2)x(x+2)=100x(x+2)x(x+2)=0
or x+2=100

Therefore, x=0,2
or x=98

But x cannot be 0
Therefore, logx is undefined fr x0
Therefore, x=98 is only solution.
