Find x if 132x = 70 eight.



Dicussion (1)

  • 132x = 708
    \( 1 × x^2 + 3 × x^1 + 2 × x^0 \)
    \( 7 × 8^1 + 0 × 8^0 \)
    \( x^2 + 3x + 2 − 56 = 0 \)
    \( x^2 + 3x − 54 = 0 \)
    x(x + 9)−6(x + 9) = 0
    (x + 9)(x − 6) = 0
    Either (x + 9) = 0 or (x − 6) = 0
    x = − 9 or +6
    The positive values for x = 6
    The base number for 132x = 1326
