So, this quadratic equation has two solutions: -1/5 and -1. Example 4. Use the quadratic formula to solve: $$9x^2 + 12x + 4 $$ The quadratic formula is $$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} $$ Here's a = 9, b = 12, and c = 4. ...
A way to solve quadractic equations is making use of this formula x =-b ±√b² - 4ac2a The part (b² - 4ac) is called the "discriminant", because it can "discriminate" between the possible types of answer. If it is positive, you will get two real solutions, if it is zero ...
