🆕 New Concept Discovered: Classifying Polynomials
Naming polynomials by degree and number of terms.
Step 1: Understand how to classify polynomials
To classify a polynomial, we first simplify it by combining any like terms. Then, we name it based on two characteristics:
- Degree (the highest exponent of the variable):
- Degree 1: linear
- Degree 2: quadratic
- Degree 3: cubic
- Number of terms (after simplifying):
- 1 term: monomial
- 2 terms: binomial
- 3 terms: trinomial
---
Step 2: Classify \( 2x - x^2 + 4x + x^2 \)
Combine like terms:
- Combine \( x^2 \) terms: \( -x^2 + x^2 = 0 \)
- Combine \( x \) terms: \( 2x + 4x = 6x \)
Simplified expression:
\[ 6x \]
- Degree: 1 (linear)
- Number of terms: 1 (monomial)
Classification: linear monomial
---
Step 3: Classify \( x^3 - 5x^2 + 3 - 2 \)
Combine like terms:
- Combine constant terms: \( 3 - 2 = 1 \)
Simplified expression:
\[ x^3 - 5x^2 + 1 \]
- Degree: 3 (cubic)
- Number of terms: 3 (trinomial)
Classification: cubic trinomial
---
Step 4: Classify \( x^3 - x^3 + x^2 - x^2 + 3 \)
Combine like terms:
- Combine \( x^3 \) terms: \( x^3 - x^3 = 0 \)
- Combine \( x^2 \) terms: \( x^2 - x^2 = 0 \)
Simplified expression:
\[ 3 \]
- Degree: 0 (constant)
- Number of terms: 1 (monomial)
Classification: constant monomial
---
Step 5: Classify \( 7x - x^2 + x^2 + 4x^2 \)
Combine like terms:
- Combine \( x^2 \) terms: \( -x^2 + x^2 + 4x^2 = 4x^2 \)
Simplified expression:
\[ 4x^2 + 7x \]
- Degree: 2 (quadratic)
- Number of terms: 2 (binomial)
Classification: quadratic binomial
---
Step 6: Classify \( -6x - x^3 + 6x - 4x \)
Combine like terms:
- Combine \( x \) terms: \( -6x + 6x - 4x = -4x \)
Simplified expression:
\[ -x^3 - 4x \]
- Degree: 3 (cubic)
- Number of terms: 2 (binomial)
Classification: cubic binomial
