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=
