Ada yg bisa bantu? Thanks

f(x) = 2^(5 - x) + 2^x - 12 = 0
=> 2^5 / 2^x + 2^x - 12 = 0 =======> misal 2^x = p
=> 32/p + p - 12 = 0 =============> kali p
=> 32 + p^2 - 12p = 0
=> p^2 - 12p + 32 = 0
=> (p - 8)(p - 4) = 0
=> p = 8 atau p = 4
=> 2^x = 2^3 atau 2^x = 2^2
=> x = 3 atau x = 2
x1 . x2 = 3 . 2 = 6
