Step-by-step explanation:
Here the given equation is
We have to factor the perfect square trinomial on the left side of the equation
So left side of the equation is
=
since [(a+b)²= a²+b²+2ab]
Therefore the factorial form of the equation will be
Now we have to solve the equation by applying square root property
