Step 1: move c to the right side of the equation.
Step 2: Make a = 1 by dividing all the numbers by a.
Step 3: Divide b by 2, then square that result. Add the final result to both sides of the equation.
Step 4: Factorise the left-hand side of the equation.
Step 5: Square root both sides.
Step 6: Solve for x.
