Introduction

Polynomials are algebraic expressions consisting of variables and coefficients combined using only addition, subtraction, and multiplication. In this article, we will explore the process of simplifying polynomials, focusing on the given polynomials $P = x^4 + 3x^3 + 2x^2 - x + 2$ and $Q = (x^3 + 2x^2 + 3)(x^2 - 2)$ . We will determine the operation that results in the simplified expression.

Understanding Polynomials

A polynomial is an expression consisting of variables and coefficients combined using only addition, subtraction, and multiplication. The variables in a polynomial are often represented by letters such as $x$ , $y$ , or $z$ . The coefficients are the numerical values associated with each term in the polynomial. For example, in the polynomial $P = x^4 + 3x^3 + 2x^2 - x + 2$ , the variables are $x$ and the coefficients are $1$ , $3$ , $2$ , $-1$ , and $2$ .

Simplifying Polynomials

To simplify a polynomial, we need to combine like terms. Like terms are terms that have the same variable raised to the same power. For example, in the polynomial $P = x^4 + 3x^3 + 2x^2 - x + 2$ , the terms $3x^3$ and $-x$ are like terms because they both have the variable $x$ raised to the power of $3$ . To simplify the polynomial, we can combine these like terms by adding or subtracting their coefficients.

Multiplying Polynomials

To multiply polynomials, we need to use the distributive property. The distributive property states that for any numbers $a$ , $b$ , and $c$ , $a(b + c) = ab + ac$ . We can apply this property to multiply polynomials by multiplying each term in one polynomial by each term in the other polynomial.

Simplifying the Given Polynomials

Let's simplify the given polynomials $P = x^4 + 3x^3 + 2x^2 - x + 2$ and $Q = (x^3 + 2x^2 + 3)(x^2 - 2)$ .

Simplifying Polynomial P

To simplify polynomial $P$ , we need to combine like terms. The terms $3x^3$ and $-x$ are like terms because they both have the variable $x$ raised to the power of $3$ . We can combine these like terms by adding or subtracting their coefficients.

import sympy as sp
x = sp.symbols('x')
P = x4 + 3*x3 + 2*x**2 - x + 2
simplified_P = sp.simplify(P)
print(simplified_P)

Simplifying Polynomial Q

To simplify polynomial $Q$ , we need to multiply the two binomials using the distributive property.

import sympy as sp
x = sp.symbols('x')
Q = (x3 + 2*x2 + 3)*(x**2 - 2)
simplified_Q = sp.simplify(Q)
print(simplified_Q)

Determining the Operation

To determine the operation that results in the simplified expression, we need to analyze the simplified polynomials $P$ and $Q$ . We can see that the simplified polynomial $P$ is a quartic polynomial, while the simplified polynomial $Q$ is a quadratic polynomial.

Conclusion

In this article, we have explored the process of simplifying polynomials, focusing on the given polynomials $P = x^4 + 3x^3 + 2x^2 - x + 2$ and $Q = (x^3 + 2x^2 + 3)(x^2 - 2)$ . We have determined the operation that results in the simplified expression by analyzing the simplified polynomials $P$ and $Q$ . The simplified polynomial $P$ is a quartic polynomial, while the simplified polynomial $Q$ is a quadratic polynomial.

Future Work

In future work, we can explore other methods for simplifying polynomials, such as using the rational root theorem or the factor theorem. We can also explore the application of polynomial simplification in various fields, such as engineering, physics, and computer science.

Q: What is the distributive property?

A: The distributive property is a property that states that for any numbers $a$ , $b$ , and $c$ , $a(b + c) = ab + ac$ . We can apply this property to multiply polynomials by multiplying each term in one polynomial by each term in the other polynomial.

Q: How do I multiply polynomials using the distributive property?

A: To multiply polynomials using the distributive property, you need to:

Multiply each term in one polynomial by each term in the other polynomial
