    Tienes que usar la fórmula cuadrática:

    (-b + / - √ (b^2-4ac)) / 2a

    Primero identificas los valores de a, b y c en kx^2-3x+2=0

    K=a, b=-3, c=2

    Luego sustituis en la fórmula y te queda:

    (3+/-√ (9-8k)) / 2k

    Para que las raíces Sena reales se tienen que cumplir que 9-8k>=0

    Step-by-step explanation:

    Therefore discriminant = b^2-4ac = 0

    b=-k, a=3, c=2

    b^2-4ac = (-k) ^2-4*3*2=0

    k^2-24=0

    k^2=24

    k = + / - 2sqrt (6)
