simplify ln(x^2-1)-ln(x+1)

Solution

simplify

ln (x^{2} - 1) - ln (x + 1)

Solution

ln (x - 1)

Solution steps

ln (x^{2} - 1) - ln (x + 1)

Apply log rule:

lo g_{c} (a) - lo g_{c} (b) = lo g_{c} (\frac{a}{b})

ln (x^{2} - 1) - ln (x + 1) = ln (\frac{x ^{2} - 1}{x + 1})

= ln (\frac{x ^{2} - 1}{x + 1})

Simplify

\frac{x ^{2} - 1}{x + 1} : x - 1

= ln (x - 1)
