Complete the square for 2x2 - 4x = 14.
o a. (x + 1)2 = 8
o b. (x-1)2 = 8
o c. (2x - 1)2 = 15
© d. (2x - 2)2 = 30

B

Step-by-step explanation:

Given

2x² - 4x = 14 ( divide through by 2 )

x² - 2x = 7

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 1)x + 1 = 7 + 1

(x - 1)² = 8 → B

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
