Find two consecutive even integers such that the square of the second, decreased by twice the first is 52

Let the first integer be . So, the next even number is

Let's translate the formula: the square of the second is , twice the first is . So, the equation is

Expand the square to get

The solutions to this equations are

So, the possible consecutive even numbers are

dwe

step-by-step explanation:

ewd

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
