Answer:

a = -10 and b = 18

Step-by-step explanation:

α = 3

β = -2

Place α and β in -

==: x² + (a+1)x + b = 0

==: (3)² + (a+1) 3 - b = 0

==: 9 + 3a + 3 - b = 0

==: 12 + 3a + b = 0

==: 3a + b = -12  ........(1)

==: x² + (a+1)x + b = 0

==: (-2)² + (a+1) (-2) + b = 0

==: 4 - 2a - 2 + b = 0

==: -2a + b = -2    .......(2)

From 1 and 2 we get,

a = -10 and b = 18
