The calculator on this page shows how the quadratic formula operates, but if you have access to a graphing calculator you should be able to solve quadratic equations, even ones with imaginary solutions.. Step 1) Most graphing calculators like the TI- 83 and others allow you to set the "Mode" to "a + bi" (Just click on 'mode' and select 'a+bi').
Assuming you're given three points along a parabola, you can find the quadratic equation that represents that parabola by creating a system of three equations. Create the equations by substituting the ordered pair for each point into the general form of the quadratic equation, ax^2 + bx + c. Simplify each equation, then use the method of your ...

To find a quadratic equation from a table, first identify the quadratic pattern (increasing or decreasing values). Determine the coefficients (linear, constant, and squared) using table values by plugging them into the equation y = ax^2 + bx + c. Then, solve the quadratic equation using factoring, the quadratic formula, or graphing. Rearrange the equation into standard form and solve for the ...

The quadratic equation is given by: ax 2 + bx + c = 0. The quadratic formula is given by: The discriminat is: Δ = b 2 -4ac The quadratic formula with discriminat is:
Quadratic Formula. The calculator uses the following formula: x = (-b ± √ D) / 2a, where D = b 2 - 4ac. This formula calculates the solution of quadratic equations (ax 2 +bx+c=0) where x is unknown, a is the quadratic coefficient (a ≠ 0), b is the linear coefficient and c represents the equation's constant. The letters a, b and c are known numbers and are the quadratic equation's ...
Quadratic formula also define the axis of symmetry of the parabola. If any equation that can be rewrite in \( ax^2 + bx + c = 0 \) form can be solved by using quadratic formula. We can also graph the function \( y = ax^2 + bx + c \). Its shape is parabola and the roots of the quadratic equation are the x-intercepts of this function.
In algebra, a quadratic equation is any polynomial equation of the second degree with the following form: ax 2 + bx + c = 0. where x is an unknown, a is referred to as the quadratic coefficient, b the linear coefficient, and c the constant. The numerals a, b, and c are coefficients of the equation, and they represent known numbers. For example, a cannot be 0, or the equation would be linear ...
