Textbook Question
In Exercises 35–44, factor the greatest common binomial factor from each polynomial.3x(x+y) − (x+y)
Verified step by step guidance1
Identify the common binomial factor in the expression. In this case, the common binomial factor is \((x+y)\).
Factor out the common binomial factor \((x+y)\) from each term in the polynomial.
Rewrite the expression as \((x+y)(3x - 1)\).
Verify the factorization by distributing \((x+y)\) back into \((3x - 1)\) to ensure it equals the original expression.
Conclude that the expression is factored correctly as \((x+y)(3x - 1)\).

1mKey Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Greatest Common Factor (GCF)
The Greatest Common Factor is the largest expression that divides two or more terms without leaving a remainder. In polynomial expressions, identifying the GCF involves finding the highest degree of common variables and coefficients among the terms. This concept is crucial for simplifying expressions and factoring polynomials effectively.
