X^2-14x-12y+73=0 find equation, vertex, focus, directrix, and focal width

Equation at the end of step 1 : x2 - 14x - 12y + 73 = 0 Step 2 : Solving a Single Variable Equation:

2.1 Solve x2-14x-12y+73 = 0

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.

We shall not handle this type of equations at this time.
