Answer:
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)
(2,-4) is a solution to the equation.
