sqrt(2x-3) = x-3

2x-3 = (x-3)^2

2x-3 = x^2-6x+9

x^2-8x+12 = 0

(x-6)(x-2) = 0 so x = 2 or 6 Do both answers solve the equation? Or is one of them extraneous? What do YOU think?

Well, yes....there is only one. Which one? Substitute x = 2 and then x = 6 into the original equation to see which one works.
