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) x^2+ 8x = 13
A. Discriminant =
B. Number of solutions for the quadratic equation =
C. Type of solutions (circle one): Real /Imaginary
D. Type of solutions (circle one): Rational/irrational

A. Discriminant = 116

B. Number of solutions for the quadratic equation = 2

C. Type of solutions (circle one):Imaginary

D. Type of solutions (circle one):irrational

Step-by-step explanation:

The given quadratic equation is

We rewrite in standard form to get;

The discriminant is

where a=1, b=8, c=-13

We substitute to get:

Since the discriminant is great than zero, we have two distinct real roots

$3,200 x 7.25% = $3,200 x .0725 = $232 interest monthly

$232 monthly x 12 annual = $2, 784
