    5.1 Solving for roots in quadratic equations
    1. Students will solve directly for quadratic equations by using square roots which are the inverses of quadratics. This is another method to solve for x when there is no linear term in the quadratic equation because it is more direct. An example is problem number 2 on worksheet 5.2 practice problems. Students will complete guided notes page 4 from 5.1.
    2. Students will use the principal square root which is often the most reasonable answer in a quadratic equation.

    4. Students will complete the guided notes page 4 of 5.1 and will try practice problems on page 233 problems 5-22.
    5. Parabolas from falling objects will be investigated and real world problems involving a pendulum and objects is space will be explored as well as prize money and company profits. (p. 234 problems 29, 30, and 32.)
    6. The homework is Worksheet 5.3 problems 1-18 all. To solve for x take the square roots of both sides of the equation.



    January 10th
    1. The students will understand that the axis of symmetry and the x point of the vertex of a parabola is halfway between the x-intercepts.
    2. The formula for the x-intercepts will be derived from this understanding and used to find the x-coordinate of the vertex of the quadratic equation.
    3. Once the x-intercept is found, it can be substituted for x in the quadratic equation and y can be found. This is the y-coordinate of the quadratic equation.
    4. The class will discuss problems 1-10 and walk through the steps and students will complete the guided notes 1-3 of 5.2.
    5. The parabola opens up or down depending on whether the coefficient a is positive or negative.

    5.4 The Quadratic Formula

    1. Students have factored equations and found the zeros in order to graph the Quadratics.
    2. Students will now be given the zeros and from that they can substitute and expand using reverse thinking and find the quadratic equation.
