Write 2x^2 – 12 x + 23 in the form a(x+b)^2 + c, where a, b, and c are integers

2(x - 3)² + 14 = 0

Step-by-step explanation:

2x² -12x + 23 = 0

2(x² - 6x) + 23 = 0

2(x² - 6x + 9) - 9 + 23 = 0

2(x - 3)² + 14 = 0

d

step-by-step explanation:

d

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
