Factor by Grouping with Gcf

Which of the following methods would be best to solve this equation by Factoring?
7x³ + 49x² = 0

• GCF

• I-Chart with Grouping (a > 1)

• Diffefernce of Squares

• Difference of Cubes

Factor out the GCF:

4x - 10

• 4(x - 5)

• 2(x - 5)

• 2(2x - 5)

• 2(2x -10)

• 2x(x + 1)(x − 1)

• 2(x² − 2)(4x − 1)

Why do we need to find the GCF of polynomials? Choose the BEST option.

• Because Ms. Rice said so

• To simplify the polynomials as much as possible before working with them

• To get rid of stuff

• Because the GCF makes the problem impossible to solve
