(a+b-1)x²+(b-c+2)x +(c-a+4) = 4x²+3x+2
______________
Términos semejantes, coeficientes iguales
a+b-1 = 4. → Alpha
______
b-c +2 = 3. → Gama
_______
c-a+4 = 2. → Beta
En alpha ;
b = 5-a
En gama ;
b = 1 + c
En beta ;
C = -2 + a
Igualando Alpha y gama
5 - a = 1 + c
4 - a = C
En betha
4 - a = -2 + a
6 = 2a
a = 3
_____
C = 1
b = 2
Piden la suma
a + b + C = 6
