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..
