When the radical terms are the same, just focus on the numbers that are in front of them so it's really just 6 - 9 and you get -3 (third root of 2b)
A would be fine as your answer.
X2 is on the right side, X1 is on the left side so -14 would be X1 and 2 would be x2
so it would be the first answer
Answer:
-7
Step-by-step explanation:
-2(x+5)=4
open the bracket with -2
-2x - 10 = 4
combine the like terms
-2x = 4 + 10
-2x = 14
divide by -2
-2x/-2 = 14/-2
x = -7
