Question

Without solving it, determine the nature of the roots of this equation:
x2 + 3x – 4 = 0

Answer 1

X =1 , -4

Answer 2

a.repeated root
b.two real roots
c.two conjugate imaginary roots
d.two nonconjugate imaginary roots
e.one complex and one real root

Answer 3

The expression inside the radical of the quadratic formula is called the discriminant.
Evaluate the discriminant for this quadratic equation.
Then once you know the discriminant, use the info below:
If it is positive, there are two real roots.
If it is zero, there is one real root.
If it is negative, there are two complex conjugate roots.
