Answer:
OPTION A: 3x - 1 = ± 5
Step-by-step explanation:
We have (3x - 1)² = 25
In OPTION A, Square root is taken on both sides.
This gives us: 3x - 1 = ± 5. And this is the logical follow - up of the previous step.
IN OPTION B: (a - b)² is wrongly expanded. So, this can not be the next step.
In OPTION C: The square root is taken only on the LHS but not on the RHS. So, it is eliminated.
In OPTION D: The square is expanded on LHS whereas on the RHS square root is taken. So, it is not correct and is eliminated.
Therefore, the correct option is A.
First, let's isolate t! Make sure to change your signs when you change from one side of the equation to the other.
3/2 + t = 1/2
t = 1/2 - 3/2
Now, we can solve for t!
t = 1/2 - 3/2
t = -2/2
t = -1
Hope this helps!
