1 answer:
Answer:
2 or C
Step-by-step explanation:
I'm taking this to mean
4 = 2(x - 1)^2
4 = 2(x^2 - 2x + 1)
4 = 2x^2 - 4x + 2
2x^2 - 4x - 2 = 0
x^2 - 2x - 1 = 0
What you get from here is sqrt(2) as one of the roots.
That is not nearly an answer.
4 = 4(x -1)
4 = 4x - 4
8 = 4x
x = 8/4
x = 2
That makes C the answer.
