Log2 (x-6) + log2 (x-4) - log2 X=2

Answer 1

[(x - 6)(x - 4)] / x = 4 ... x^2 - 10 x + 24 = 4 x ... x^2 - 14 x + 24 = 0

(x - 12) (x - 2) = 0

x = 12 , x = 2

logs are not defined for negative values ... x = 12

Answer 2

The answer is 8

Answer 3

Why does the textbook answer key say the answer is 12?????
