1. 4
2. 9
3. 21
are the answers
Answer:
5
Step-by-step explanation:
b is at 15
n is at 10
hence -15 - -10=5
positive 5 btw
The 8th character would be 58
Discussion
The discriminate is b^2 - 4*a*c
The general equation for a quadratic is ax^2 + bx + c
In this equation's case
a = 1
b= -5
c = - 3
Solve
(-5)^2 - 4*(1)*(-3)
25 - (-12)
25 + 12
37
Note
Since the discriminate is > 0, the roots are real and different. The roots do exist and there are 2 of them.
