Question

factor 21x + 21y - 56.
write your answer as a product with a whole number greater than 1.

Explanation:

Step1: Find the GCF of 21, 21, and 56.

The factors of 21 are 1, 3, 7, 21. The factors of 56 are 1, 2, 4, 7, 8, 14, 28, 56. The greatest common factor (GCF) is 7.

Step2: Factor out the GCF from each term.

\(21x + 21y - 56 = 7(3x + 3y - 8)\)

Answer:

\(7(3x + 3y - 8)\)
