Jared Haynes · Answer 1

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.

X^2-6x+9=5

(x-3) (x-3) = 5

(x-3) = 5
