The 6 in 216 is in the ones place.
Answer:
Step-by-step explanation:
Answer:
x = 1 ± 
Step-by-step explanation:
Given
2x² - 4x = 10 ( divide through by 2 )
x² - 2x = 5
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 1)x + 1 = 5 + 1
(x - 1)² = 6 ( take the square root of both sides )
x - 1 = ±
( add 1 to both sides )
x = 1 ±
← exact solutions
12.
3/4 of a foot = 9”
