Answer:

-25/12

Step-by-step explanation:

==: 6x² + x - 2 = 0

==: 6x² + 4x - 3x - 2 = 0

==: 2x ( 3x + 2 ) - 1 (3x + 2 ) = 0

==: ( 3x + 2 ) ( 2x - 1 ) = 0

==: x = -2/3 and 1/2

Zeroes = -2/3 (A) and 1/2 (B)

==: A/B + B/A

==: (-2/3 ÷ 1/2) + (1/2 ÷ -2/3)

==: (-2/3 * 2) + (1/2 * -3/2)

==: (-4/3) + (-3/4)

==: -25/12
