Question

For the​ following, find the​ discriminant, and then determine whether one​ real-number solution, two different​ real-number solutions, or two different imaginary number solutions exist.

For the following, find the discriminant, b-4ac, and then determine whether one real-number solution, two different real-number solutions, or two different imaginary number solutions exist. x2+2x+7 0 What is the discriminant, b2-4ac? (Simplify your answer.) What is the nature of the solution(s)? O A. There are two different imaginary-number solutions. O B. There are two different real-number solutions. O C. There is one real-number solution.

Answer 1

2 in equation axbc 0

if discriminant b2-4ac 0 then 2 real solutions 0 then 1 real repeated solution and if <0 then 2 imaginary solutions

discriminant 22 -4 1 7

discriminant 4-28

discriminant=-24

it has 2 imaginary different solutions
