Describe three different ways to solve a quadratic equation. describe the strengths and limitations of each method, and explain how you would decide which one to use to solve a particular problem. derive the quadratic formula from the standard form (ax2 + bx + c = 0) of a quadratic equation by following the steps below. divide all terms in the equation by a. subtract the constant (the term without an x) from both sides. add a constant (in terms of a and b) that will complete the square. take the square root of both sides of the equation. solve for x. write a linear equation that intersects y = x2 at two points. then write a second linear equation that intersects y = x2 at just one point, and a third linear equation that does not intersect y = x2. explain how you found the linear equations.
