Uincy uses the quadratic formula to solve for the values of x in a quadratic equation. he finds the solution, in simplest radical form, to be x = . which best describes how many real number solutions the equation has?

2 solutions

Step-by-step explanation:

A quadratic equation has the formula:

The solution of the equation is given as:

The expression: is known as the discriminant given by the symbol D.

Thus, the discriminant D, is given as D = b² - 4ac

There are several conditions to the solution.

If D < 0 the roots are imaginary. They are not real.  

If D = 0, the solution has one real root

If D > 0, the solution as two distinct real roots (negative or positive)

A quadratic equation has only two real roots or solutions.

it is probably the graph on the bottom right.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
