Answer: -2,2
Step-by-step explanation:
x² – 3x – 3 = 0
First, add 3 to both sides
x² – 3x – 3 (+3)= 0 (+3)
x² – 3x = 3
Solve for a. 2ax = -3x; a = -3/2
x² - 3x + (-3/2)² = 3 + (-3/2)²
Simplify
x² - 3x + (-3/2)² = 21/4
Complete the square
(3 - 3/2)² = 21/4
solve:
x - 3/2 = √(21/4); x = (√21 + 3)/2
x - 3/2 = -√(21/4); x = ((-√21) + 3)/2
Answers:
x = ((√21) + 3)/2 & x = ((-√21) + 3)/2
hope this helps

The probability of getting six in first time is 1/6.
Probability shows possibility to happen an event, it defines that an event will occur or not. The probability varies from 0 to 1.
Given that,
Lynn rolls a fair die.
Since, there are 6 faces on die.
In which 1, 2, 3, 4, 5, and 6 are shown.
The find probability of getting 6 in first time,
Use formula,
Probability = favorable outcome / total outcome
= 1 / 6
= 0.666
The required probability is 1/6.
