Answer:
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
D) a+2c=10.5
Since b=c+
a+b+c=10
a+(c+1/2)+c=10
a+2c+1/2=10
a+2c=9.5
Since b=c+
a+b+c=10
a+(c+1/2)+c=10
a+2c+1/2=10
a+2c=9.5
