However, sometimes a quadratic function does not factor easily, or at all. In these situations, in order to determine the real roots, if they exist, we must use the quadratic formula. Given a quadratic formula in standard form, {eq}f(x) = ax^2 + bx + c {/eq}, the quadratic ...
Amy has worked with students at all levels from those with special needs to those that are gifted. So, what have we learned? We've learned that a quadratic equation is an equation of degree 2. The standard form of a quadratic is y = ax^2 + bx + c, where a, b, and c are ...
