Yes, that can be done. A quadratic equation ##(x\, , \,ax^2+bx+c)## is a parabola. You basically computed where the symmetry axis of a standard parabola lies by determining the x-coordinate of the minimum (##a>0##) or maximum (##a<0##), and then the distance to its two zeros (so they exist).

The quadratic equation is a polynomial equation of the form ax^2 + bx + c = 0, where a, b, and c are constants and x is the variable. It represents a parabola on a graph and has two solutions, or roots, which can be found by using the quadratic formula or by differentiating the equation.
Differentiation is a mathematical process that involves finding the rate of change of a function. In the case of a quadratic equation, the derivative (or rate of change) of the equation will give us the slope of the parabola at any given point. By setting the derivative equal to zero and solving for x, we can find the x-values where the slope is equal to zero, which are the roots of the quadratic equation.
Yes, all quadratic equations can be solved by differentiation. However, the process may not always be the most efficient or practical method, as it involves finding and solving the derivative of the equation. In some cases, using the quadratic formula or factoring may be a quicker and simpler approach.
One limitation of using differentiation is that it can only find real roots of a quadratic equation. If the equation has complex roots, differentiation will not work. Additionally, if the equation is not in standard form or has additional terms, the derivative may be more complicated and difficult to solve.
Yes, a strong understanding of calculus is necessary to use differentiation to find the roots of a quadratic equation. This method requires knowledge of derivatives, setting equations equal to zero, and solving for x. Without a solid understanding of these concepts, it may be difficult to successfully use differentiation to find the roots of a quadratic equation.
