Its easy to calculate y for any given x. Need more problem types. Substituting in the quadratic formula Since the discriminant b 2 4 ac is 0 the equation has one root.
The multi-step process may seem tedious but it is the most consistent method of finding the x-intercepts.
In algebra a quadratic equation is any polynomial equation of the second degree with the following form. The numerals a b and c are coefficients of the equation and they represent known numbers. X is the variable or unknown we dont know it yet. For example we have the formula y 3x 2 - 12x 95.
