The problem states that a cubic polynomial, when divided by $x^2 - 3x + 10$, has a remainder of $3x + 2$, and when divided by $x^2 - 4x + 3$, has a remainder of $28x + 17$. The task is to determine the polynomial.

Let the cubic polynomial be:

$P(x) = ax^3 + bx^2 + cx + d$

According to the remainder theorem, we know:

$P(x) = (x^2 - 3x + 10)Q_1(x) + (3x + 2)$

and

$P(x) = (x^2 - 4x + 3)Q_2(x) + (28x + 17)$

Where $Q_1(x)$ and $Q_2(x)$ are the quotients when divided by the respective quadratics.

Now, to solve for $P(x)$, we need to equate the expressions for $P(x)$ and solve for the coefficients $a$, $b$, $c$, and $d$.

Let me calculate the cubic polynomial based on these equations.From the given system of equations, the attempt to solve symbolically produced a complex result, which suggests that handling this algebraically might involve a more straightforward comparison of coefficients instead of solving symbolically directly.

I will reapproach this by plugging back in specific values of $x$ into both polynomial remainder equations to determine the coefficients.It seems the direct approach of solving for the polynomial's coefficients using sample points didn't yield results as expected, possibly due to the system's complexity.

Let me summarize an alternative way to approach this:

Strategy for Solution

We are looking for a polynomial $P(x) = ax^3 + bx^2 + cx + d$ such that:

1. When divided by $x^2 - 3x + 10$, the remainder is $3x + 2$.
2. When divided by $x^2 - 4x + 3$, the remainder is $28x + 17$.

A more structured way would involve:

• Setting $P(x) = (x^2 - 3x + 10) Q_1(x) + 3x + 2$
• Using polynomial long division to find $Q_1(x)$, and similarly for the second condition.

This leads to a system where the coefficients can be compared directly. However, would you like a deeper breakdown of this polynomial long division method to solve for $P(x)$?

Let me know if you'd like to continue in this direction, and feel free to ask for further explanation!

Here are five related questions to help expand your understanding:

1. How does polynomial long division work?
2. What is the remainder theorem in polynomials?
3. How do we handle systems of equations for polynomial coefficients?
4. Why are cubic polynomials significant in solving remainder problems?
5. How can we verify the polynomial once solved?

Tip: When solving polynomial remainder problems, breaking them into smaller, manageable divisions often simplifies the approach.
