simplify ln(x^2-6x-16)-ln(x+2)

Solution

simplify

ln (x^{2} - 6 x - 16) - ln (x + 2)

Solution

ln (x - 8)

Solution steps

ln (x^{2} - 6 x - 16) - ln (x + 2)

Apply log rule:

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

ln (x^{2} - 6 x - 16) - ln (x + 2) = ln (\frac{x ^{2} - 6 x - 16}{x + 2})

= ln (\frac{x ^{2} - 6 x - 16}{x + 2})

Simplify

\frac{x ^{2} - 6 x - 16}{x + 2} : x - 8

= ln (x - 8)
