Odpowiedź:
lewa strona= kpx²-kpx-mpx+mp= kpx²- ( kp+mp)x +mp
12 x²- 46 x +20
...........................................................................................................
kp=12 kp+mp=46 mp=20
p=12/k p(k+m)=46 k≠0 m*(12/k)=20
12m=20k 3m= 5k
m= 5k/3
......................
p(k+m)=46
12/ k (k+ 5k/3) =46
12+ 20k=46
20k=34
k=17/10
...........................
p=12:k= 12*10/17=120/17
................................................
m= 5/3 k= 5/3 * 17/10=17/6
