To solve the given by , we will start by writing all the terms on the left-hand side. Then, we will factor out the .
We have rewritten the left-hand side as a of two . Now, we will apply the to solve the equation.
From Equation (I), we found that one solution is
To find other solutions, we will solve Equation (II). Note that this is a . Thus, we will use the .
To do so, we first need to identify
We see that
Let's substitute these values into the formula and solve for
This solution to the quadratic equation is also solution for the given equation.
