For example, the quadratic equation : has solutions : Since is not any real number, both of these solutions for x are complex numbers.
If this distance term were to decrease to zero, the axis of symmetry would be the x value of the zero, indicating there is only one possible solution to the quadratic equation.
First Course" Because the quadratic equation involves only one unknown, it is called " univariate ".
For example, the quadratic formula (which is the solution of the quadratic equation ) appears as: The formula is printed in a way a person would write by hand, or typeset the equation.
