Question

Find the solutions to x^2=18

Answer 1

Answer:

x= ±2√3

Step-by-step explanation:

To eliminate x, you have to square root 18 and x

Answer 2

Hm, so we are supposed to find X? No problem!

$x^{2} =18$

Now to solve this equation, first you must get "x" by itself.

(aka: without the square root)

$\sqrt{x}^{2} =\sqrt{18}\\\\\sqrt{18}=+(or)-3\sqrt{2}$

Now that we have determined that, the answers you seek are:

$x=3\sqrt{2},\:x=-3\sqrt{2}$
