Evaluate the discriminant of the equation. Tell how many solutions each equation has and whether the solutions are real or imagi

cupoosta [38]

Answer:

D=-4<0, the equation has no real solutions, it has two imaginary solutions.

Step-by-step explanation:

The quadratic equation $x^2 +4x+5=0$ has coefficients

a=1,

b=4,

c=5.

The discriminant D is the expression

$D=b^2-4ac.$

Hence,

$D=4^2-4\cdot 1\cdot 5=16-20=-4$

Since the discriminant is negative, the equation has no real solutions, it has two imaginary solutions.
