Question

Aflati numerele intregi a si b stiind ca :
a). a·b=-14 si IaI =2;
b). Ia·bI=24 si a=-6.

Answer 1

a) a={-2,2}
b={-7,7}
b) b={-4,4}

Answer 2

a)
a*b=-14
a={-14 , -7, -2, 1, 2, 7, 14}
b={1, 2, 7, -14, -7, -2, -1)
|a|=2,
a=2, b=-7
a=-2,b=7

b)
|a*b|=24
a*b=24
a  poate lua valorile: 1,2,3,4,6,8,12,24 cu plus si cu minus
b  poate lua valorile: 24,12,8,6,4,3,2,1 cu plus si cu minus

a*b=-24
a={-24,-12,-8,-6,-4,-3,-2,-1,1,2,3,4,6,8,12,24}
b={1,2,3,4,6,8,12,24,-24,-12,-8,-6,-4,-3,-2,-1}
pentru a=-6 , din ambele situatii rezulta b={-4,4}
