Name:__________ warm-up 4-4 Solve x 2 – x = 2 by factoringSolve c 2 – 16c + 64 = 0 by factoring Write a quadratic equation with the roots –1 and 6 in the form ax 2 + bx + c, where a, b, and c are integers.

2
Solve 2x 2 + 5x + 3 = 0 by factoring In a rectangle, the length is three inches greater than the width. The area of the rectangle is 108 square inches. Find the width of the rectangle.

3
Details of the Day EQ: How do quadratic relations model real-world problems and their solutions? Depending on the situation, why is one method for solving a quadratic equation more beneficial than another? How do transformations help you to graph all functions? Why do we need another number set? I will be able to… Activities: Warm-up Collect Lab Project Review homework Notes: 4-4 Complex Numbers Class work/ HW Vocabulary: imaginary unit pure imaginary number complex number complex conjugates. Perform operations with pure imaginary numbers. Perform operations with complex numbers.
