Para encontrar los ceros, iguala la función a cero

f(x) = 6x^{2} + 12x -7

Agrupa términos con la misma variable y mueve la constante al lado opuesto de la ecuación

6x^{2} + 12x -7=0

Factoriza el coeficiente principal

7= 6x^{2} + 12x

Completa el cuadrado. Recuerda equilibrar la ecuación agregando la misma constante a ambos lados

7= 6(x^{2} + 2x)

7+6= 6(x^{2} + 2x+1)

13= 6(x^{2} + 2x+1)

Reescribe como cuadrados perfectos

13= 6(x+1)^{2}

(13/6)=(x+1)^{2}

x+1=(+/-)\sqrt{\frac{13}{6}}

x=-1(+/-)\sqrt{\frac{13}{6}}

x1=-1+\sqrt{\frac{13}{6}}

x2=-1-\sqrt{\frac{13}{6}}

por lo tanto

la respuesta es

Los ceros de la función cuadrática son

x=-1+\sqrt{\frac{13}{6}} y x=-1-\sqrt{\frac{13}{6}}

Leona [12618]

Response:

1/6

Detailed explanation:

Let

c -----> the count of cola bottles chosen by Dan

s -----> the count of smarties selected by Dan

m -----> the count of marshmallows selected by Dan

we have

c=3s -----> A equation

m=2s -----> B equation

we understand that

To determine the fraction of the sweet bag that consists of smarties, we must divide the number of smarties by the total amount of sweets

The overall number of sweets is calculated as

(c+s+m)

substituting equations A and B into the total sweets

(3s+s+2s) =6s

Calculate the fraction

s/6s

Reduce it

1/6

For the first film he may pick any of 6 options; once that choice is made, 5 remain for the second, then 4 for the third, and so forth.

Hence the total is 6! = 6*5*4*3*2 = 720 possible orders
