Have you ever looked at a polynomial and wanted to know how many specific values can hold a secret formula? Today, we’re diving into the thrilling world of polynomials—specifically, how to determine the values of \( k \) for the polynomial \( x^2 + kx + 36 \) that will give us two distinct integer roots.
This topic may sound a bit daunting at first, but fear not! With our easy-to-follow guide, you’ll be solving these polynomials like a pro in no time.
Understanding the Fundamentals
Before we start crunching numbers, let’s set the stage.
Imagine that finding the roots of a polynomial is like searching for two missing puzzle pieces in a jigsaw puzzle. These puzzle pieces (roots) must fit perfectly to complete the picture (the polynomial). However, we not only want any two pieces; we’re interested in distinct pieces that together add up to a specific combination!
For the polynomial \( x^2 + kx + 36 \):
1. \( k \) represents our variable.
2. The root puzzle pieces multiply to give us 36.
To find \( k \), we’ll explore how the roots relate to \( k \) through Vieta’s formulas.
Step-by-Step Solution
Here’s how we can systematically discover the potential values of \( k \):
1. Roots Representation: Let’s denote the roots as \( r_1 \) and \( r_2 \). According to Vieta’s formulas, we have:
\[
r_1 + r_2 = -k
\]
\[
r_1 \cdot r_2 = 36
\]
2. Finding Factor Pairs: Our mission now is to unearth all integer pairs that multiply to give us 36 while being distinct!
Some possible pairs include:
– (1, 36), (2, 18), (3, 12), (4, 9)
– Negative pairs: (-1, -36), (-2, -18), (-3, -12), (-4, -9)
3. Calculating k: For every valid pair, we compute:
\[
k = -(r_1 + r_2)
\]
4. Distinct Values Verification: We keep a tally of these \( k \) values to ensure they are distinct!
Implementing the Logic in Python
Now, let’s jump into some code (our trusty sidekick) that helps automate this process:
import itertools
# Define the product we are interested in
product_36 = 36
factor_pairs = []
# Find all pairs (r1, r2) such that r1 r2 = 36
for i in range(1, product_36 + 1):
if product_36 % i == 0:
pair = (i, product_36 // i)
if pair[0] != pair[1]: # Ensure distinct pairs
factor_pairs.append(pair)
# Calculate k for each pair and ensure distinct integer roots
valid_k_values = set()
for r1, r2 in factor_pairs:
k = -(r1 + r2)
valid_k_values.add(k)
print((len(valid_k_values), sorted(valid_k_values)))
What Does the Code Do?
Think of the code as a treasure map leading us to our distinct values of \( k \):
– The first part of the code finds all pairs of integers that multiply to 36, similar to finding matching socks in a drawer.
– It ensures those socks (or pairs) are different using a simple check—not wearing the same one twice!
– Finally, the code computes \( k \) and keeps only the unique values, much like collecting only the rarest stamps in a postcard collection.
After running the code, we find four distinct values for \( k \):
– -37, -20, -15, and -13.
Thus, our answer is 4 values of \( k \) allow the polynomial to have two distinct integer roots!
Troubleshooting Tips

– Ensure you have Python installed and properly configured.
– Check for any indentation errors in the code.
– Double-check that the code runs in an environment where the `itertools` module is available.
