Does anyone mind me with this? it seems simple enough.

the question is: radical x-3 = radical x + 3 (the +3 is outside of the radical). we are solving for x in this question.

x = 4

Step-by-step explanation:

It is given that , and we have to solve the given equation for x.

Now, we have

Squaring both sides we get  

⇒ x - 3 = x + 6√x + 9 {Since we know the formula of (a + b)² = a² + 2ab + b²}

⇒ 6√x = - 12

⇒ √x = -2

Again squaring both sides we get  

⇒x = 4 (Answer)

i think it is 18
