Question

PLS HELP. WILL MARK BRAINLIEST IF CORRECT! Is the first step in solving x-1 squared=8 different from the first step of solving x squared-1=8? Explain
A. Yes, in the first equation, start by subtracting 8 from both sides to set the equation equal to zero, but in the second equation, start by adding 1 to both sides to isolate the radical.


B. Yes, in the first equation, start by squaring both sides to eliminate the radical, but in the second equation, start by adding 1 to both sides to isolate the radical.

C. No, to solve either equation, square both sides to eliminate all radicals.


D. No, to solve either equation, isolate the radical by adding 1 to both sides.

Answer 1

Answer:

B.

Step-by-step explanation:

First Equation. (x - 1)² = 8

1. (x - 1) = √8

2. x - 1 + 1 = 2√3 + 1

3. x = 2√3 + 1

3.

Second Equation. x² - 1 = 8

1. x² - 1 + 1 = 8 + 1

2. x² = 9

3. x = ±3
