Answer:
B. (5x - 4)(3x + 2)
Step-by-step explanation:
Factor the following:
[tex] \longrightarrow [/tex] 15x² - 2x - 8
The coefficient of x² is 15 and the constant term is -8. The product of 15 and -8 is -120. The factors of -120 which sum to -2 are 10 and -12.
So,
[tex] \longrightarrow [/tex] 15x² + (10 - 12)x - 8
[tex] \longrightarrow [/tex] 15x² + 10x - 12x - 8
[tex] \longrightarrow [/tex] 5x(3x + 2) - 4(3x + 2)
[tex] \longrightarrow [/tex] (5x - 4)(3x + 2)
