Given that the difference between the roots of the equation

is

.
Recall that the sum of roots of a quadratic equation is given by

.
Let the two roots of the equation be

and

, then

. . . (1)
Also recall that the product of the two roots of a quadratic equation is given by

, thus:

. . . (2)
From (1), we have:

Substituting for alpha into (2), gives:
This statement is false.
If he were to double the amount that Emily has to get franks, franks would have more.
Look :)
Emily's = 300
Frank's = 300 x 2 = 600
now...
Emily's = 300
Frank's = 600
So frank has more! NOT fewer.
Answer:
≈2.69
≈-0.19
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. You have that the quadratic formula is:

2. To solve the quadratic equation you must substitute the values. So, you have that:
Rewrite the equation:


Then you have:

3. Therefore, you obtain the following result:
≈2.69
≈-0.19

(18×2) + 2n=58
36+2n= 58
2n=58-36
2n= 22
n= 22÷2
n= 11
