Bantuin satu soal aja , besok harus kumpul

2^(x² - 5x + 3) = 1/(8^(x - 2))
2^(x² - 5x + 3) = 8^-(x - 2)
2^(x² - 5x + 3) = 8^(-x + 2)
2^(x² - 5x + 3) = (2³)^(-x + 2)
2^(x² - 5x + 3) = 2^(-3x + 6)

Maka
x² - 5x + 3 = -3x + 6
x² - 5x + 3x + 3 - 6 = 0
x² - 2x - 3 = 0
(x - 3)(x + 1) = 0
• x = 3 misalkan a = 3
• x = -1 misalkan b = -1

Jadi, a + b = 3 + (-1) = 2

Jawabannya B
