To solve the given by , we will start by factoring 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 .
To do so, we first need to identify
We see that
Let's substitute these values into the formula and solve for
We will now find the first and second solutions by using the positive and negative signs.
These solutions to the quadratic equation are also solutions for the given equation.
