Answer:
roots are -5/2 or 6
factors are (2x + 5) (x - 6)
Step-by-step explanation:
-4x² + 14x + 60 = 0
-2(2x² - 7x - 30) = 0
2x² - 7x - 30 = 0
2x² - 12x + 5x - 30 = 0
2x (x - 6) + 5 (x - 6) =0
(2x + 5) (x - 6) =0
factors are (2x + 5) (x - 6)
roots are: (2x + 5) = 0 (x - 6) = 0
2x = -5 x = 6
x = -5/2
x = -5/2 or 6
hope this helps you dear..
