Thank you for explaining. But, as for ②, " the domain of x " is not taken into account.
If the problem were log[10]((2x-3)(x+1))=1, the answer could be -13/8. But the problem is log[10](2x-3) - log[10](x+1) = 1 .
According to the logarithmic function's definition, 2x-3>0 and x+1>0 . Therefore, x should be " x>3/2 " . (It includes x > -1 .)
・・・・・ Judging from this, -13/8 cannot be the solution. I guess there is no solution. ????
