log2(x)+log2(x−2)=3

Simplify the left side.

log2(x2−2x)=3

Rewrite log 2(x2−2x)=3

in exponential form using the definition of a logarithm. If x and b

are positive real numbers and b≠1

, then logb(x)=y is equivalent to by=x.23=x2−2x

Solve for X

x=4,−2

Exclude the solutions that do not make

log 2(x)+log2(x−2)=3true.
