Question

(4x-2)(5+3x)-(12x²-3x+1)≤0

2 Réponse

  • (4x-2)(5+3x)-(12x²-3x+1)≤0
    20x + 12x² - 10 - 6x - 12x² + 3x - 1≤0
    15x ≤ 11
    x  ≤ 1.36

  • (4x-2)(5+3x) - (12x²-3x+1) ≤ 0
    20x -10 + 12x² - 6x - 12x² + 3x - 1 ≤ 0
    12x² - 12x² - 6x  + 3x + 20x - 1 -10 ≤ 0
    - 6x  + 3x + 20x -11 ≤ 0
    17x -11 ≤ 0
    17x ≤ 11

    x
    ≤ [tex] \frac{11}{17} [/tex]
