Step 1: Add the opposite of the constant term to both sides:
Step 2: Multiply both sides by the reciprocal of the lead coefficient:
\ =\ \frac{1}{4}\left(-20\right))
Step 3: Divide the first degree term coefficient by 2 and square the result. Add that result to both sides: (8 divided by 2 is 4, 4 squared is 16)
Step 4: Factor the perfect square trinomial in the RHS.
^2\ =\ 11)
Step 5: Take the square root of both sides, remembering to consider both the positive and negative roots.
Step 6: Add the opposite of the constant term in the LHS to both sides.
