Question 141096
adding logs is multiplying quantities


taking antilog __ x(x^2-9)=-5x __ x^3-9x=-5x __ x^3-4x=0 __ x(x^2-4)=0 __ x(x+2)(x-2)=0


x=0


x+2=0 __ x=-2


x-2=0 __ x=2


logarthms are NOT defined for quantities <=0
__ the algebra generates the "solutions" __ but the logs aren't realistic
