9-4 Solving Quadratic Equations Using Square Roots – We learned that when the quadratic equation is in the form ax2 + bx = c, it can be solved by isolating the ax2 term, simplifying to remove the coefficients, and then taking the square root of each side of the equation. We practiced several of these type of problems where we take the square root and have two possible solutions. Next we reviewed completing the square to find the answers to a quadratic equation that is not able to be factored.
Assignment: Complete the assigned problems for homework.
9-5 Completing the Square – We learned to complete the square by adding the square of half of the coefficient of the x to each side of the equation. Then we solved quadratic trinomials by completing the Square to what completing the Square to write a quadratic equation in Vertex form.
