Math Problem Statement
x^4-14x+24
Solution
Let's analyze and solve the polynomial by finding its roots or simplifying further.
Step 1: Analyze the polynomial
This is a fourth-degree polynomial: It does not appear to have any obvious factorization as a sum or difference of terms. We will try to solve it by:
- Checking for possible rational roots using the Rational Root Theorem.
- Factoring further, if possible.
Step 2: Rational Root Theorem
The Rational Root Theorem suggests that any rational root is of the form: where:
- are the factors of the constant term (24): ,
- are the factors of the leading coefficient (1): .
This gives the potential rational roots:
Step 3: Test roots
Substitute these into to find any that satisfy .

Step 4: Numerical approximation
If no rational roots exist, we approximate the real roots using methods such as Newton's method or graphing. Let me know if you'd like further exploration of this!
