We want to solve the by . To do so, we will start by rewriting the equation so all terms with
are on one side of the equation and the constant is on the other side.
Now let's divide each side by
so the of
In a quadratic expression,
is the coefficient of the
-term. For the equation above, we have that
Let's now calculate
Next, we will add
to both sides of our equation. Then, we will factor the on the left-hand side, and solve the equation.
We will now find the first and second solutions by using the positive and negative signs.
