Create And Solve Quadratic Equations
Akopọ
Quadratic equations describe the shape of a thrown ball, the area of a rectangle and countless other situations where a quantity depends on the square of another. Solving them means finding the values that make the equation true, and there is more than one route to the answer.
In this lesson you will create quadratic equations from problems and solve them four ways: by inspection, by factoring, by the quadratic formula, and by completing the square. Knowing all four lets you pick the fastest method for each equation and check one against another.
