Step-by-step explanation:
Answer:
- -3
- 1.5(1 + i√3)
- 1.5(1 - i√3)
Step-by-step explanation:
- y³ + 27 = 0
- (y + 3)(y² - 3y + 9) = 0
1. y + 3 = 0 ⇒
2. y² - 3y + 9 = 0
- y = (3 ±√(3² -4*9))/2
- y = (3 ± √-27)/2
- y = (3 ± i√27)/2
- y = 3/2(1 ± i√3)
- y = 1.5(1 ± i√3)
Answer:
Your answer is D.
36x2-25 is equivalent to (6x)2-(5)2
Step-by-step explanation:
Simple solution: Put each equation into a graphing calculator and look at the tables, they are exactly the same.
