Find all real solutions of the polynomial equation 
a. 
b. 
c. 
d. 
If an argument reads
If ?ABC is an equilateral triangle with perimeter 3s units then each edge of ?ABC is s units long. If each edge of an equilateral triangle is s units long then its height is ?3s/2 units. If the height of an equilateral triangle is ?3s/2 units, then its area is ?3s2/4 units2. Then we can deduce (a) If ?ABC is an equilateral triangle with perimeter 3s units then its area is ?3s2/4 units2. (b) If the area of ?A|BC is| ?3s2/4 units2 then it is an equilateral triangle (c) If each edge of an equilateral triangle is s units long then its area is ?3s2/4 units2. (d) All of these are valid conclusions. (e) Both (a) and (c) are correct.
