Question

How do I solve: 4 = (x + 1/2)^2?

Answer 1

well.....take a square root on both sides.

x + 1/2 = +/- 2.
So, x = 3/2 or -5/2

Answer 2

so... 4 will be +/- 2, and then x + 1/2?

Answer 3

Yes.

Answer 4

x + 1/2 = 2 OR x + 1/2 = -2
x = 3/2 OR x = -5/2

Answer 5

but why is it (x + 1/2)^2?

Answer 6

Is it not what is given in the problem?
