Discriminant is -29, and there are 0 real solutions

Discriminant is 11, and there are 2 real solutions

Discriminant is 29, and there are 2 real solutions

Discriminant is -11, and there are 0 real solutions

Question 2

Discriminant is -89, and there are 0 real solutions

Discriminant is 13, and there are 2 real solutions

Discriminant is 89, and there are 2 real solutions

Discriminant is 0, and there is 1 real solution

Question 3

Question 4

Question 5

a = 5    b =  4     c =  13

a = 13   b =  5    c =  4

a = 4    b =  -13    c =  5

a = 5    b =  13     c =  4

Given the following quadratic, using the quadratic formula, what would be the correct solution?

Given the following Quadratic Formula for an equation, what are the values for a, b, and c?

a = 5    b =  4     c =  13

a = 13   b =  5    c =  4

a = 4    b =  -13    c =  5

a = 5    b =  13     c =  4
