Question

26. A student is asked to solve the equation

4(3x - 1)² 17 = 83. The student's
solution to the problem starts as
-
4(3x - 1)² = 100
(3x - 1)² = 25
A correct next step in the solution of the
problem is
A. 3x1 = ±5
B. 3x - 1 = ±25
C. 9x² - 1 = 25
D. 9x² - 6x +1=5

Answer 1

Answer: A

Explanation:

The next step you would take is take the square root of both sides to cancel out the square.

Which gets rid of the square on 1 side and you get ±5 on the other.
