Answer: The required solution of the given equation is x = 5, -5.
Step-by-step explanation: We are given to solve the following quadratic equation using the square root method :

In square root method, we need to take the square roots on both sides of teh equation to find the solution.
From equation (i), we have
![x^2=25\\\\\Rightarrow x=\pm\sqrt{25}~~~~~~~~~~~~~[\textup{taking square roots on both sides}]\\\\\Rightarrow x=\pm\sqrt{5^2}\\\\\Rightarrow x=\pm5.](https://tex.z-dn.net/?f=x%5E2%3D25%5C%5C%5C%5C%5CRightarrow%20x%3D%5Cpm%5Csqrt%7B25%7D~~~~~~~~~~~~~%5B%5Ctextup%7Btaking%20square%20roots%20on%20both%20sides%7D%5D%5C%5C%5C%5C%5CRightarrow%20x%3D%5Cpm%5Csqrt%7B5%5E2%7D%5C%5C%5C%5C%5CRightarrow%20x%3D%5Cpm5.)
Thus, the required solution of the given equation is x = 5, -5.
