you really shouldn't; the "solution" or "roots" or "zeroes" of a quadratic are usually required to be in the "exact" form of the answer. You canusethe rounded form when graphing (if necessary), but "the answer(s)" from the Quadratic Formula should be written out in the (often mes...
The meaning of QUADRATIC FORMULA is a formula that gives the solutions of the general quadratic equation ax2 + bx + c = 0 and that is usually written in the form x = (-b ±√(b2 — 4ac))/(2a).
For writing a quadratic equation in standard form, the x2 term is written first, followed by the x term, and finally, the constant term is written.Further, in real math problems the quadratic equations are presented in different forms: (x - 1)(x + 2) = 0, -x2 = -3x + 1, 5x(...
Using this formula, you can find the solutions to any quadratic equation. Note that there are three possible options for obtaining a result: The quadratic equation has two unique roots when Δ > 0. Then, the first solution of the quadratic formula isx₁ = (-B + √Δ)/2A, and the ...
The standard form of a quadratic equation is written as follows: $$ax^2 + bx + c = 0 ; a \ne 0 $$ Conceptually, quadratic equations are used to identify the roots, or zeros, of a quadratic function; namely, the x-values where the graph of f(x) intercepts the x-axis. When ...

Understanding the properties of a quadratic equation and how to recognize them when written out, it is natural to wonder what a quadratic equation looks like when graphed? That's a great question! To answer this, consider the simplest quadratic equation, the function {eq}y = x^2 {/eq}. ...
Another common form is called vertex form, because when a quadratic is written in this form, it is very easy to tell where its vertex is located. The vertex form is given by:f(x)=a(x−h)2+kf(x)=a(x−h)2+k The vertex is ...
So a quadratic equation can be written as x2−(α+β)x+αβ=0, This is the quadratic formula. Geometric Approach of Understanding Root of Quadratic Equation Consider the equation of Parabola y=ax2+bx+c, by the root of this equation we mean where the x-axis cuts the graph of thi...
