={4,8,12,14}
Answer:
Just take L. C. M it's really simple
We do completing the square as follows:
1. Put all terms with variable on one side and the constants on the other side.
<span>5x^2 - 3x = 25
2. Factor out the coefficient of the x^2 term.
</span>5(x^2 - 3x/5) = 25
3. Inside the parentheses, we add a number that would complete the square and also add this to the other side of the equation. In this case we add 9/100 and on the other side we add 9/20.
5(x^2 - 3x/5 + 9/100) = 25 + 9/20
4. We simplify as follows:
5(x^2 - 3x/5 + 9/100) = 25 + 9/20
5(x - 3/10)^2 = 509/20
(x - 3/10)^2 = 509/100
x1 = √(509) /100 + 3/10
x2 = -√(509) /100 + 3/10

Step-by-step explanation:
Im not sure, but i think these are the answers
Since we are already given the equation, we can already solve for the given problems above. Let us start with part 2 so we can easily answer part 1.
Part 2: the cost to get started before any books are printed. Using the equation, x = 0. So, y =1250+25(0)
y= 1250
So the cost to get started before any books are printed is 1250.
Now, to part 1, let us say, only 1 book is printed. So x=1
y = 1250 +25(1)
y= 1250 +25
y = 1275
So, for 1 book is 1275, and no book is 1250. This gives us the answer that the change in the total cost for each book printed would be $25. Hope this is the answer that you are looking for.
