Math Problem Statement
Solution
Let's solve the polynomial and express it in factored form as requested in the image.
Step 1: Rewrite in Standard Form
The given polynomial is already close to standard form but we can rearrange it as: This is the standard form of the cubic equation.
Step 2: Use Synthetic Division to Find Roots
To use synthetic division, we first try to find possible rational roots using the Rational Root Theorem. The possible rational roots are the factors of the constant term (50) divided by the factors of the leading coefficient (1). So, the possible roots are:
Let's try some values by substituting them into the polynomial:
- For : So, is a root.
Step 3: Perform Synthetic Division
We divide by .
The coefficients of the polynomial are: .
Performing synthetic division:
2 & 1 & -2 & -25 & 50 \\ & & 2 & 0 & -50 \\ \hline & 1 & 0 & -25 & 0 \\ \end{array}$$ The quotient is $$x^2 - 25$$ with no remainder, meaning the factorization so far is: $$(x - 2)(x^2 - 25) = 0$$ ### Step 4: Factor $$x^2 - 25$$ The expression $$x^2 - 25$$ is a difference of squares, which factors as: $$x^2 - 25 = (x - 5)(x + 5)$$ ### Step 5: Final Factored Form Thus, the factored form of the polynomial is: $$(x - 2)(x - 5)(x + 5) = 0$$ ### Step 6: Complete the Fill-in-the-Blank Questions - The polynomial equation has at most **3** real roots. - The leading term is **$$x^3$$**. - The leading coefficient is **1**. - The degree is **3**. - The roots or zeros of the polynomial are **2, 5**, and **-5**. - The factors are $$(x - 2), (x - 5), (x + 5)$$.
