Answers & Comments
Answer:
1. 4h² - 25
(2h)² - (5)²
(2h + 5)(2h - 5)
2. (2u - 3v)(3m - 4n) - (2u - 3v)(m + 2n)
(2u - 3v)(3m - 4n - m - 2n)
(2u - 3v)(2m - 6n)
3. 10ax² + 14a²x
2ax(5x + 7a)
4. (2c - 9e)(4c + 5e)
8c² + 10ce - 36ce - 45e²
8c² - 26ce - 45e²
5. c² - 8c - 20
c² - 10c + 2c - 20
c(c - 10) + 2(c - 10)
(c - 10)(c + 2)
6. 2d(3m - 4n) - 3e(3m - 4n)
(3m - 4n)(2d - 3e)
