tolong dong no. 6 + caranya

1 Jawaban

  • X²+(2p-3)x+2p-19=0
    tentukan a,b,c
    a = 1
    b = 2p-3
    c = 2p-19
    cari nilai p
    x1 + x2 = -b/a
    = -2p-3/1
    = -2p-3 = 0
    •p= -3/2

    hasil kali akar-akar = c/a
    jadi, c/a = 2p-19/1
    = 2p-19
    = 2(-3/2) - 19
    = -3-19
    = -22 jawabannya E
