Answer:
Step-by-step explanation:
The best way to answer this is to graph it before using the quadratic formula. The graph is shown below.
Notice that the minimum doesn't come anywhere near the x axis. That means when you use the quadratic formula, you are going to get the square root of a negative number. Check out the discriminate.
√(b^2 - 4*a * c)
a = 1
b = 6
c = 10
√(36 - 4*1*10
√36 - 40
√-4
2*i
So there is no point going any further. You have no real roots.
Answer:
The first customer that will get four free tickets is 50th customer
Step-by-step explanation:
Find the least common multiple of numbers 10 and 25. First, factorize these numbers:
When finding LCM, first write the all common multiples (underlined 5) and then multiply them by remaining multiples (2 and 5). You get 50 as LCM(10,25). This means that each 50th customer will get four free tickets.
