Answer:
B
Step-by-step explanation:
A:
Completing the square: (x+ 7/2)^2 = -2 + 49/4 = 41/4, in the next step you'll be square rooting a positive number so it'll have real roots.
B:
Completing the square: (x+3/2)^2 = -9 + 9/4 = -27/4, you'll next be square rooting a negative number, so it'll have complex roots
C:
Completing the square: (x-5/2)^2 = -1 + 25/4 = 21/4, next you'll square root a positive number, so real roots
D:
Completing the square: (x+7/2)^2 = 2 + 49/4 = 57/4, square root a positive number, so real roots.
Answer:
1/6
Step-by-step explanation:
The die is rolled once, so it is 1 out of the total number on the die ie 6, as a die has only faces or sides so its obvious out of these 6 faces only one will show.
√5 (10-4√2)
=10√5-4√10
The answer is D
