Answer:
x = 3, x = 6
Step-by-step explanation:
Using the rules of logarithms
log x - log y = log ( )
log ⇔ nlog x
x = n ⇔ x =
Given
2 x -
(x - 2) - 2 = 0 ( add 2 to both sides )
x² -
(x - 2) = 2
(
) = 2
= 3² = 9 ( multiply both sides by x - 2 )
x² = 9(x - 2) ← distribute
x² = 9x - 18 ( subtract 9x - 18 from both sides )
x² - 9x + 18 = 0 ← in standard form
(x - 3)(x - 6) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x - 6 = 0 ⇒ x = 6
