Identifica los coeficiente en la siguiente ecuación: 3x2−6x+2=0
a= 3 b=−6 c=−2
a= 3 b=−6 c=2
a= 3 b=6 c=2
3
Multiple Choice
¿Cuál sería el reemplazo correcto en la fórmula cuadrática ? 3x2−6x+2=0
x=2(3)−(−6)±(−6)2−4(3)(2)
x=2(3)−6±(−6)2−4(3)(2)

SOLUCIOˊN DE
x=2(3)−(−6)±(−6)2−4(3)(2)
x=6+6±36−24
x=66±12
x1=6(6+12) ≈1,58
x2=6(6−12) ≈0,42
5
Multiple Choice
Identifica los coeficientes en la siguiente ecuación 3x2−10x=8
a= 3, b=−10, c= 8
a= 3, b=10, c= 8
a= 3, b=−10, c= −8
6
Multiple Choice
¿Cuál sería el reemplazo correcto en la fórmula cuadrática? 3x2−10x−8=0
x=2(3)−(−10)±(−10)−4(3)(−8)
x=2(3)−(−10)±(−10)2−4(3)(−8)
7
Multiple Choice
El resultado de simplificar la expresión x=2(3)−(−10)±(−10)2−4(3)(−8) es:
x=610±100+96=610±196=610±14
x=610±100−96=610±4=610±2
8
Multiple Select
¿Cuáles son las dos soluciones de la ecuación cuadrática 3x2−10x−8=0 ?
x1=610+14=6 24=4, x2=610−14=6 −4=−32
