Answer

2$a^{2}$(4a - b)(3a + 2b)

Work Step by Step

1. Factor out GCF from each term (2$a^{2}$): 2$a^{2}$(12$a^{2}$ + 5ab - 2$b^{2}$) 2. Factor expression inside parentheses: 2$a^{2}$(4a - b)(3a + 2b) 3. Check: 2$a^{2}$(4a - b)(3a + 2b) = 2$a^{2}$(12$a^{2}$ + 5ab - 2$b^{2}$) = 24$a^{4}$ + 10$a^{3}$b - 4$a^{2}b^{2}$
