Proof of the quadratic formula
Examples of the quadratic formula to solve an equation
Quadratic equations are polynomials to the second degree.
In an exam, any question that asks for an answer to a quadratic equation
We are going to take the cofficients of each term in this quadratic equation
So, the equation can be solved using the quadratic formula.
A quadratic equation will have two solutions, known as roots, although these
Quadratic Formula for the TI-83 and 84
The Quadratic Formula can be used to find the roots of any quadratic
See: The Quadratic Equation, Formula, & Discriminant

video explains the discriminant and types of roots to a quadratic equation
graph of a quadratic equation Consider a quadratic function given by y =f(x)
All Quadratic Equations have the general form:
Here we got the quadratic formula, so there shouldn't be any difficulties
Quadratic Formula:
One common use of quadratic equations is computing trajectories in
Note that in Example 1 we solve a generic quadratic equation by completing
Of course, not all quadratic equations will have x-intercepts but they will
That's the formula used for solving the quadratic equation no less.
