Here's a pattern to consider:
1+100=101
2+99=101
3+98=101
4+97=101
5+96=101
.....
This question relates to the discovery of Gauss, a mathematician. He found out that if you split 100 from 1-50 and 51-100, you could add them from each end to get a sum of 101. As there are 50 sets of addition, then the total is 50×101=5050
So, the sum of the first 100 positive integers is 5050.
Quick note
We can use a formula to find out the sum of an arithmetic series:

Where s is the sum of the series and n is the number of terms in the series. It works for the above problem.

Answer:
The solutions to the quadratic function are:

Step-by-step explanation:
Given the function

Let us determine all possible solutions for f(x) = 0

switch both sides

subtract 3 from both sides

simplify

Divide both sides by 4


Add (-1/2)² to both sides




solving

∵ 
as

so

Add 1/2 to both sides


also solving


Add 1/2 to both sides


Therefore, the solutions to the quadratic function are:
