Akar akar persamaan 2x pangkat 2 -3x-5=0

2 Jawaban

  • 2x^2 - 3x - 5 = 0
    (2x - 5)(x + 1) = 0

    2x - 5 = 0
    2x = 5
    x = 5/2

    x + 1 = 0
    x = -1

    Hp = { -1 , 5/2 }
  • 0 = 2x^2 - 3x - 5
    0 = ( 2x - 5 ) ( x + 1 )

    0 = 2x - 5
    5 = 2x
    x = 5/2

    0 = x + 1
    -1 = x

    HP : { -1 , 5/2 }
