Domanda del libro di testo
In Exercises 35–44, factor the greatest common binomial factor from each polynomial. 4x²(3x−1) + 3x − 1
Guida verificata passo dopo passo1
Identify the common binomial factor in the expression: \(4x^2(3x-1) + 3x - 1\).
Notice that the binomial \((3x - 1)\) appears in both terms: \(4x^2(3x-1)\) and \(3x - 1\).
Factor out the common binomial \((3x - 1)\) from the entire expression.
Rewrite the expression as \((3x - 1)(4x^2 + 1)\).
Verify the factorization by expanding \((3x - 1)(4x^2 + 1)\) to ensure it equals the original expression.

Factoring Polynomials
Factoring polynomials involves breaking down a polynomial into simpler components, or factors, that when multiplied together yield the original polynomial. This process is essential for simplifying expressions and solving equations. In this case, recognizing common factors within the polynomial helps in rewriting it in a more manageable form.

Greatest Common Factor (GCF)
The Greatest Common Factor (GCF) is the largest factor that divides two or more numbers or expressions without leaving a remainder. In polynomial expressions, identifying the GCF allows for the extraction of common terms, simplifying the polynomial and making it easier to work with. This is crucial for factoring out the common binomial factor in the given expression.
