Use the quadratic equation x^2+3x+5=0 to answer the questions. A: What is the discriminant of the quadratic equation? B: Based on the discriminant, which statement about the number and type of solutions to the equation is correct?

A: 11
A: 29
A: βˆ’11
A: βˆ’29
B: The equation has two complex solutions.
B: The equation has one repeated real solution.
B: The equation has two real solutions.

Respuesta :

Answer:

A: -11

B: Two complex solutions

Step-by-step explanation:

The discriminant of this equation is 3^2-20=9-20=-11. Since the discriminant is negative, its square root will be an imaginary number, and there will be two complex solutions. Hope this helps!

Answer:

A:-11

B: has no real solutions

Step-by-step explanation:

For this equation: a=1, b=3, c=5

1x2+3x+5=0

Step 1: Use quadratic formula with a=1, b=3, c=5.

x=
