Algebraic Expressions: The Greatest Factor of All True or False

1. What is the greatest common factor in the expression 6x2y + 4xy - 10y - 20y2? -> 2y
2. What is the greatest common factor in the expression 9x3yz + 6x2y - 18x5z? -> 3x2
3. Using the distributive property on the expression - ( - 2 + 5x) produces -> 2 + 5x
4. Multiply 3a(a + 2b). -> None of the above
5. Multiply out the expression  using the distributive property. What is the greatest common factor in the resulting expression?  -> 2x2
6. Factor the expression - 2x - 4y. ->  - 2(x + 2y)
7. Which of the following statements is true? -> 3x and 2y are terms in the expression 2x - 3y.
8. Factor abc + 3a2bc + ab2c3. -> abc(1 + 3a + bc2)
