We see that in these 3 terms, 6 is a common factor. So, let's factor out a 6:

We can set this equal to 0 and factor by using the quadratic formula which is:

So, let's do just that:

Note that the 6 goes away if you divide both sides by 6. In this case, a = 1, b = -1, and c = -2. Let's plug that into the quadratic equation:


So, we can write this as:

Notice that the 6 comes back because it was only temporarily mad. And that the roots have opposite signs in the parentheses because to find the roots, you need to set each parentheses equal to 0 and solve for n. With that in mind, your final answer is 6(n-1)(n+2). Hope I could help you!
Answer: There is 680% increase for the fund.
Step-by-step explanation:
Since we have given that
Number of shares they purchased = 1000
Cost of per share at the time of their marriage = $10
So, Amount of fund will be

Cost per share after 30 years = $78
So, Amount of fund will be

Percentage of increase for the fund will be given as

Hence, there is 680% increase for the fund.
