5 天之前 · Example #2: Solve 2x² + 2x -12 = 0 For our next quadratic formula example, we will again start by identifying the values of a, b, and c as follows: a=2. b=2. c=-12. Make sure that you correctly identify the sign (positive or negative) as well, since this is necessary to using to quadratic formula correctly.

The solution (s) to a quadratic equation can be calculated using the Quadratic Formula: The "±" means we need to do a plus AND a minus, so there are normally TWO solutions ! The blue part (b2 - 4ac) is called the "discriminant", because it can "discriminate" between the possible types of answer: when it is negative we get complex solutions.
