Answer:
2(5+6)
Explanation:
First, find the GCF of 10 and 12. (The GCF is the largest number that divides evenly into both 10 and 12.)
To find the GCF, list the factors of each number and find the largest common factor. The factors of 10 are 1, 2, 5, and 10. The factors of 12 are 1, 2, 3, 4, 6, and 12. The largest number which goes into both numbers (common factor) is 2.
Factor out the GCF from both 10 and 12. Factoring means to divide a number by its factors.
10 divided by 2 is 5, and 12 divided by 2 is 6. So, 10 + 12 can be rewritten as 2(5 + 6).
Therefore, using the GCF and factoring, 10 + 12 can be rewritten as 2(5 + 6).
