Use the properties of logarithms to expand the following expression as much as possible. Simplify any numerical expressions that can be evaluated without a calculator.

Question

ln(5x²−40x+60)

Answer 1

lnABC = lnA + lnB + lnC

5x^2 -40x + 60 =

5(x-6)(x-2)

ln(5x^2-40x + 60) = ln5 + ln(x-6) + ln(x-2)
