And if we put the values of roots or x in the Left-hand side of the equation, it will equal to zero. Just put the values of a, b and c into the Quadratic Formula, and do the calculations. These roots … Using the quadratic formula is required if the roots are decimal.. 2. Therefore, they are called zeros. Negative 3 times negative 1 is 3. 2 If we divide each term by a, then the quadratic equation can be expressed in an equivalent form with the coefficient of x2is equal to one as shown below. And you get a negative number in the square-root, it is the case of quadratic equations with complex roots. Only if it can be put in the form ax 2 + bx + c = 0, and a is not zero.. Here are some examples: But sometimes a quadratic equation doesn't look like that! Imagine if the curve "just touches" the x-axis.
