You came up with the ambiguous answer by solving the equation using square roots. However, if you treated the problem as a quadratic equation, you would have solved it with one definitive answer: 24. (x-12) squared equals x2 - 24x +144. (x2 would be read as "x squared" as I cannot write exponents on my computer.). Thus, the equation would now read: x2 - 24x + 144 = 144. If you subtract 144 from both sides, you get x2- 24x = 0. Then, if you divide both sides by x, you would get x - 24 = 0. Finally, if you add 24 to both sides, you come up with the final answer: x = 24.
x=0 or 24
0 or 24 in 2 secs
Not even. When the equation comes to view, 0 was the first thing comes to mind. 24 was a bit later.

0 is also the zero , sir you did it wrong in last step you have to take x common so it would be x(x-24) = 0 thus x = 0 and x = 24 both r ans
24
