Use a table of values and a given graph to find the solution to a quadratic equation.

The student is expected to:Ī(8)(B) solve quadratic equations having real solutions by factoring, taking square roots, completing the square, and applying the quadratic formulaĪ(8)(A) write, using technology, quadratic functions that provide a reasonable fit to data to estimate solutions and make predictions for real-world problems Definition quadratic equation is a polynomial equation of the form Whereis called the leading term, (or constantterm). The student formulates statistical relationships and evaluates their reasonableness based on real-world data. The simplest Quadratic Equation is: f (x) x 2 And its graph is simple too: This is the curve f (x) x2 It is a parabola. Maybe we can guess an answer Then check if we are right. The student applies the mathematical process standards to solve, with and without technology, quadratic equations and evaluate the reasonableness of their solutions. Guess and Check Example: what are the factors of 2x2 + 7x + 3 No common factors. There are different methods you can use to solve quadratic equations, depending on your particular problem. Let's investigate ways to use a table of values to represent the solution to a quadratic equation.Ī(8) Quadratic functions and equations.
