Completing the Square: Finding the Vertex. {*style:<i><b>Completing the Square: The vertex form of a quadratic is given by = ( – ) 2 + , where ( , ) is the vertex.
The " " in the vertex form is the same " " as in = 2 + + (that is, both 's have exactly the same value). The sign on " " tells you whether the quadratic opens up or opens down. Factoring Quadratics: The Simple Case. Factoring Quadratics: The Simple Case (page 1 of 4) Sections: The simple case, The hard case, The weird case A "quadratic" is a polynomial that looks like "ax2 + bx + c", where "a", "b", and "c" are just numbers.
For the easy case of factoring, you will find two numbers that will not only multiply to equal the constant term "c", but also add up to equal "b", the coefficient on the x-term. For instance: Spask.
