Use the discriminant to determine the number of solutions and types of solutions for the quadratic equation, below. Then answer the questions in the box. (4 points) a^2+8a=13 Discriminant = Number of solutions for the quadratic equation = Type of solutions (circle one): Real /Imaginary Type of solutions (circle one): Rational/irrational

answer:

The discriminant is the (b^2-4ac) part of the quadratic formula...in this case:

64-48=16

So there will be two real rational solutions.

The rule:

If discriminant<0, there are no real solutions (although there are two imaginary solutions)

If discriminant=0, there is only one real solution.

If discriminant>0, there are two real solutions.
