Factor the algebraic expression completely by grouping terms: ax + 2bx - 3ay - 6by.
Answer and explanation
Correct answer: C. (a + 2b)(x - 3y)
- Step 1: Group in pairs: (ax + 2bx) - (3ay + 6by). Step 2. Factor common terms from each group: x(a + 2b) - 3y(a + 2b). Step 3. Factor common binomial (a + 2b): (a + 2b)(x - 3y). Answer: (a + 2b)(x - 3y). Why not the others: Sign errors in the other three factorizations.
