Answer:
x= 
Step-by-step explanation:
Given: 
This is a quadratic equation.

Taking common 3 from the equation given
⇒ 
dividing both side by 3
⇒
By using different factor, we can observe this trinomial can not be factored.
∴ solving it by completing the square.
⇒ 
adding 9 on both side
⇒ 
To get a perfect square number as coeffecient of x is 4, lets add both side by 4.
⇒
we know, 
∴ 
Taking Square root on both side, remember; √a²= a
⇒ 
opening parenthesis
⇒ 
subtracting both side by 2
∴ x=
