Algebra-1

Question Analysis
This question tests the ability to factor a multivariable polynomial using the grouping method, which is a fundamental skill in Algebra-1.

Key Concept Explanation
Grouping involves dividing the polynomial into two groups and factoring out the greatest common factor (GCF) from each group. If the resulting expressions have a common factor, it can be factored out to complete the decomposition.

Step-by-step Solution
1. Group the polynomial as .
2. Factor out the GCF from the first group: .
3. Factor out the GCF from the second group:
