Answer:
Irrational
Step-by-step explanation:
The square root of 28, which is 5.291502622129181, is not a rational number. It cannot be written as a simple fraction, so it is called irrational.
Step-by-step explanation:
4/10 is 4 away from 0 (not counting the zero but if you did is 5 away from 0) 7/10 is 3 away from 4/10 and 2/10 is 2 behind 4/10
Answer:
<u>[x - (4 + 2√3)] and [x - (4 - 2√3)]</u>
Step-by-step explanation:
Given :
Divide throughout by 3 to simplify :
- 1/3 x (3x² - 24x + 12)
- x² - 8x + 4
Using the Quadratic Formula :
- x = -b ± √b² - 4ac / 2a
- x = -(-8) ± √(-8)² - 4(1)(4) / 2(1)
- x = 8 ± √64 - 16 / 2
- x = 8 ± √48 / 2
- x = 8 ± 4√3 / 2
- x = 4 ± 2√3
Factors are :
- <u>[x - (4 + 2√3)] and [x - (4 - 2√3)]</u>
