The given expression, 81a^6 - 100, is a difference of two squares. The first term 81a^6 is a square of 9a³. The second term, 100, is a square of 10. The factors of the given expression is therefore, (9a³ - 10) x (9a³ + 10).
Answer: 6(3x + 4y)
1. Find the GCF (the largest number that goes into both 18x AND 24y). This would be 6.
2. Factor out the 6 by dividing each of the terms by the GCF
18x/6 = 3x
24y/6 = 4y
3. Write as a factored expression
6(3x + 4y)
