The factors of thirty are
1,2,3,5,6,10,15,30
Using the quadratic equation instead of calculus, you can find the x coordinate of the vertex as it will be the midpoint of the two x coordinates of the zeros...
x=(-3±√-27)/2
x=-1.5±√-6.75
That the second term is imaginary does not matter because we will add or subtract this value from -1.5, thus the midpoint of the zeros, the x coordinate of the vertex is -1.5. And to find the value of y for the vertex we just find the value of y when x=-1.5
y(-1.5)=6.75
Since y>0, the vertex is above the x-axis.

The situation in which the quotient of -24 divided by 3 be used to answer the question is;
- Julia withdrew a total of $24 from her bank account over 3 days. She withdrew the same amount each day. By how much did the amount in her bank account change each day?
<h3>Algebra</h3>
Check all options:
A. The temperature of a substance decreased by 24∘C per minute for 3 minutes. What was the overall change of the temperature of the substance?
Temperature decrease = 24°C per minutes × 3 minutes
= 72°C decrease in temperature
B. A football team lost 24 yards on one play, then gained 3 yards on the next play. How many total yards did the team gain on the two plays?
Loss = -24 yards
Gain = 3 yards
Total gain = -24 + 3
= -21 yards
C. Julia withdrew a total of $24 from her bank account over 3 days. She withdrew the same amount each day. By how much did the amount in her bank account change each day?
Amount withdrawn per day = -$24 / 3
= -$8 per day
Change in her account per day = $8
D. A cookie jar contains 24 cookies. Each child receives 3 cookies. How many children are there?
Number of children = 24 cookies / 3 cookies
= 8 cookies per children
