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.
