Mat126 Survey of Mathematics - Prime Numbers
by Angel
Please help explain this I am very lost!! Thanks
Project # 2
Task: To produce prime numbers as solutions by substituting x in the formula
x2 – x + 41
Please note you MUST show your work (plugging the number into the formula and simplifying).
Here is an example of showing your work. Let’s say I start with 3 as one of my odd numbers of choice. I need to plug 3 into the formula like this:
32 – 3 + 41
= 9 – 3 + 41
= 6 + 41
= 47
Is 47 prime? Yes! In this case, the formula produced a prime number!
Please perform the above steps for all five of your numbers (0, two even numbers of your choice, and two odd numbers of your choice).
*** Note: this is NOT an equation. Instead, it is a FORMULA. Please do NOT set the formula equal to 0 and try to factor, because this is not correct. J
Step 1: First even number of your choice: plug in number into formula and simplify:
Step 2: Second even number of your choice: plug in number into formula and simplify:
Step 3: First odd number of your choice: plug in number into formula and simplify:
Step 4: Second odd number of your choice: plug in number into formula and simplify:
Step 5: Plug in 0 into formula and simplify:
