Option 2.
shows the correct way to use the quadratic formula to solve the given equation.
Step-by-step explanation:
Step 1:
For an equation of the form
the solution is
.
Here a is the coefficient of
, b is the coefficient of x and c is the constant term.
can also be written as 
Comparing
with
, we get that a is 1, b is -4 and c is -21.
To get the solution, we substitute the values of a, b, and c in
.
Step 2:
Substituting the values, we get


This is option 2.
