Mathematicians have been searching for a formula that yields prime numbers. One such formula was
x2 − x + 41. Select some numbers (at least five different numbers for five different problems)for x, substute them in the formula, and see if prime numbers occur. Try to find a number for x that when substituted in the formula yields a composite number.

Please help me in detail choose several numbers which I can see the work from your detailed steps; I want to learn, so bad. I completed my part I assignment, but left this part out, so I got half my grade, but my instructor has permitted me to to complete my assignment in full; had not realized I left so much work out. Thnaks so much!!!
