Four? Factoring Graphing Quadratic Equation Completing the Square There may be more, but there's at least four.
The roots of the quadratic equation are the x-intercepts of the curve.
y = 2x2 - 3x - 1 = 0 After graphing this equation on my calculator, I found that there are in fact two answers, but neither of them are integers. This means that it is impossible to factor this quadratic equation in the form (x + a)(x + b) with a and b being integers.
By using the quadratic equation formula
Graph the equation then find the x intercepts.
A graphing calculator is a calculator with the capability of graphing an equation on a built-in coordinate grid on the screen. They usually have a simple LCD grid screen, and by typing in the equation (e.g., 5x+3), the screen refreshes to display a graph of the equation in a set window range.

It is used to solve quadratic equations that cannot be factored. Usually you would factor a quadratic equation, identify the critical values and solve, but when you cannot factor you utilize the quadratic equation.

A graphing calculator is used to plot graphs and solve equations. Most graphing calculators are programmable so one can create customized programs.
By using the quadratic equation formula
The quadratic formula is used to solve the quadratic equation. Many equations in which the variable is squared can be written as a quadratic equation, and then solved with the quadratic formula.
2nd [CATALOG], solve( , enter equation, variable and guess after the bracket, close brackets with " ) ". You can also put lower and upper bounds after the guess.
The quadratic formula cannot be used to solve an equation if the coefficient of the equation's x2-term is 0.
