Answer: 64.60
Step-by-step explanation:
lets do 6.80x9
= 61.20
for the half an hour, divide 6.80 by 2
it would be 3.40
61.20+3.40= 64.60
The number -5 would go to the left of a number scale. Typically because all negatives move to the left of zero on the number scale.
Given:
The equation is
To find:
The number of roots and discriminant of the given equation.
Solution:
We have,
The highest degree of given equation is 2. So, the number of roots is also 2.
It can be written as
Here, 
.
Discriminant of the given equation is
Since discriminant is 
, which is greater than 0, therefore, the given equation has two distinct real roots.
