To solve a quadratic equation, you want one side to be zero. Subtracting 2 from each side:
Then we'll put the terms in "proper" order (highest exponent to lowest):
Now we factor:
Next we use the Zero Product Property which tells us that for any product, like this one, to be zero one of its factors must be zero. So: or
Solving these... or or
Both of these are real numbers.
