  • 3^(x+1) + 6(3^(x-2)) = 3^x + 8
    (3³ + 6) × 3^(x - 2) = 3^x + 8
    (27 + 6) × 3^(x - 2) = 3^x + 8
    33 × 3^(x - 2) - 3^x = 8
    (33 - 3²) × 3^(x - 2) = 8
    (33 - 9) × 3^(x - 2) = 8
    24 × 3^(x - 2) = 8
    3^(x - 2) = 8/24
    3^(x - 2) = ⅓
    3^(x - 2) = 3`¹
    x - 2 = -1
    x = 1

    = 4x² - 1
    = 4(1)² - 1
    = 4 - 1
    = 3
