You can put this solution on YOUR website! use the substitution:
Complete the square
Take the square root of both sides
and also:
------------------
check:
OK
You can check the other answer
You can put this solution on YOUR website! .
Solve for x
log(base 4) x + log(base 4) (x-2) = 1
-----------------------------------------
It is equivalent to
x*(x-2) = 4, (1)
= ,
= = = .
So, the solutions of the equation (1) are and .
Only positive value x = satisfies the original equation.
