Question

Is this correct?
Discriminant and real number solutions

Answer 1

x^2 + 6x - 3 = 0

a = 1, b = 6, c = -3
Formula = b^2 - 4ac
6^2 - 4 * 1 * (-3) =
36 - 4 * 1 * (-3) =
36 - 4 * (-3) =
36 - (-12) =
48
Discriminant = 48
The quadratic equation has two real number solutions because the value of the discriminant is positive.

Answer 2

correct

Answer 3

Thanks:)

Can you check 6 more?

Answer 5

Goodness.... 6 more x_x

Just find the rules for discriminants and their solutions, haha.
