3x^2 - x - 2 = 0.my homework wants me to solve this quadratic equation and show all the work

x = 1, -2/3

Step-by-step explanation:

1.

Use the Quadratic Formula.

-b ± √b^2 - 4(ac)

over 2a.

2.

Substitute a = 3, b = -1, and c = -2

1 ± √(-1)^2 - 4((3)(-2))

over 2(3)

3.

Simplify.

x = 1 ± 5 / 6

4.

Answer.

x = 1, -2/3

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
