Answer:


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)

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

The answer should be 6f. You multiply the 3 and the 2 and then put the f at the end (:
