Use the properties of logarithms to expand the following expression as much as possible. Simplify any numerical expressions that can be eval

The thing to expand is this 

ln(4x^2−36x+72)

ln(4x^2−36x+72)  =        take out the GCF  =  4

ln ( 4 [ x^2 - 9x + 18 ] ) =      factor  again

ln [ 4 ( x - 3) ( x - 6 ) ] =   

Use the property that.....  ln (a * b * c)  =  ln a + ln b + ln c

ln 4  +  ln ( x - 3)  +  ln ( x - 6)
