Pertanyaan

1. 3x - 2y =
2. x² - 11x + 30 =
3. x² + 5x - 14 =
4. 3x² + 17x -10 =
5. 5x² + 13x - 6 =

2 Jawaban

  • 1. 3x - 2y = 1/6(18x - 12y)

    2. x² - 11x + 30 = (x - 5)(x - 6)

    3. x² + 5x - 14 = (x + 7)(x - 2)

    4. 3x² + 17x -10 = (3x - 2)(x - 5)

    5. 5x² + 13x - 6 = (5x - 2)(x +3)
  • 1. 3x -2y = 3x - 2y
    2. (x-6)(x-5)
    3. (x+7)(x-2)
    4. x = -2/3 dan -5
    5. (5x-2)(x+3)
