Algebra-1

Step 1: Rearrange the Equation

First, we need to move -4 to the left side:

 

Step 2: Rewrite in Standard Form

Next, we can multiply through by -1 to simplify our calculations:

 

Step 3: Use the Quadratic Formula

Now, we apply the quadratic formula, which is given by:

Here, we have:

(a = 1)(b = -2)(c = 4)

 

Step 4: Calculate the Discriminant

Next, we calculate the discriminant :

 

Step 5: Substitute into the Quadratic Formula

Now we substitute (a), (b), and the discriminant back into the quadratic formula:
