Question

Solve for x: (x – 4)2 = 2

A. x = 4 ± 2

B. x = 4 ±

C. x = 4 ±

D. x = 4 ± 2

Answer 1

Is that 2 times x - 4?

Answer 2

No its \[(x - 4)^2 = 2\]

Answer 3

For choices B and C, it's 4 plus or minus....?

Answer 4

A. \[x = 4 ± 2\sqrt2 \]
B. \[x = 4 ± \sqrt13\]
C. \[x = 4 ± \sqrt2\]
D. \[ x = 4 ± 2\sqrt13\]

Sorry about the confusion

Answer 5

Well, to get rid of the squared, you have to take the square root on both sides.

Answer 6

making the x's x^2 and taking the radical sign out from each equation, right?

Answer 7

Well, square rooting the left side would remove the exponent of 2 from the (x-4) and squaring rooting the right side would make the 2 into \[\sqrt{2}\]
