We evaluate b^2 - 4ac.  If the answer is positive, then there are two real solutions.  If it is zero, there is one real solution.  If it is negative, there are 2 complex solutions.  In this equation, a = 1, b = 5, c = 7.  Now we plug in the numbers.

5^{2}-4*1*7=1

Because this answer is positive, there are two real solutions.

How to I put x>-2.5 on a number line?
AysviL [449]

Answer:

Open circle. Points right

Step-by-step explanation:

The reason for it is because this symbol > represents greater than when it comes to inequalities. When it is an open circle that means that you are not including the number. So that also means that the -2.5 is not included to the inequality equation but it can be any other number other than that number.
