93 books
Step-by-step explanation:
Divide 744 by 8
4. -1
5. +_ 2/5
6. 3.5
this should be right
angle a is 60 degrees
The discriminant equals to 0
We have to remember our discriminant rules;
d > 0, we have 2 real roots
d = 0, we have 1 real root
d < 0, we have 2 complex roots
number one is the last one
second is the third
third is the last
