Question

Which of the following statements follows from (x - 3)^2 = 5?

Answer 1

X^2-6x+9=5
(x-3)(x-3)=5
(x-3)=5
x

Answer 2

Expand the equation by multiplying it with itself: (x-3)*(x-3)

x^2 - 3x - 3x + 9 = 5
x^2 - 6x + 9 = 5
x^2 -6x +4 = 0

Since this is not part of the choices, try a different approach. Take the square root of both sides:

x - 3 = square root of 5
x - 3 = +/- 2.24

I guess this is the middle term which is incomplete. The first and last choices are not equivalent to the given equation.
